As already stated at the beginning, the best match-ups are against control (chances to win are almost 70%) and aggro (around 71% chance to win). This deck is weak against certain combo decks, namely Amulet of Bloom (chances to win are only around 40%) and it has big problems with Infect (chances to win are around 50%).
If your meta consists mainly of control and aggro decks, this deck is the right choice.
Sideboards of G/W Auras differ from one version to another. For example, I chose to run blue cards in my sideboard because my meta requires this move, yet you most probably will not find these blue card in other sideboards. I also play Seal of Primordium as there are Chalice of the Void in the sideboards. If there are no Chalices in your meta, run Nature's Claim instead. Here is how I sideboard:
_________________________________________________________________________
U/R Twin - fair matchup
They are relying on the combo against bogles. We have to be quick and hopefully have a Path to Exile or Qasali Pridemage response ready. Our situation gets better after sideboarding as we have a plenty of hate cards against them.
In: 1x
Suppression Field
, 2x Seal of Primordium, 2x Swan Song, 2x Gaddock Teeg
Out: 2x Spirit Mantle, 2x Unflinching Courage, 2x Spirit Mantle, 1x Keen Sense
_________________________________________________________________________
Abzan - bad matchup
Game one is a gamble and it matters a lot on who is on the play. If bogles are on the draw and opponent plays turn one Thoughtseize, life gets miserable for bogles. Liliana of the Veil is something that can easily disrupt bogles as well. Life gets better after sideboarding as Leyline of Sanctity stops both Lili and the discard spells.
In: 4x Leyline of Sanctity, 1x
Suppression Field
, 1x Spell Pierce
Out: 1x Qasali Pridemage, 1x Keen Sense, 3x Spider Umbra, 1x Path to Exile
(If they are likely to play
Back to Nature
in the sideboard, side in 2x Swan Song).
_________________________________________________________________________
Affinity - good matchup
Affinity as an aggro deck is our favourable match up. Lifelink, first strike and Path to Exile are the paths to the victory.
In: 2x Seal of Primordium, 1x Stony Silence, 1x
Suppression Field
Out: 1x Keen Sense, 1x Unflinching Courage, 1x Spider Umbra, 1x Spirit Mantle
_________________________________________________________________________
Amulet Bloom - bad matchup
They can combo quickly and there is almost no way how to interact with them. The main hope is to race them as quickly as possible and send any Primeval Titans that would show up on the Path to Exile.
In: 1x
Suppression Field
, 2x Swan Song, 1x Spell Pierce, 2x Seal of Primordium
Out: 2x Unflinching Courage, 1x Keen Sense, 3x Spider Umbra
(If you feel that they might bring in the Spellskite, you may side in Stony Silence. If you think that they keep in the Hive Mind combo (which they are likely not), you may side in the Gaddock Teeg.)
_________________________________________________________________________
Burn - good matchup
We are quick for them. Especially if they are on the creature plan, it will be hard for them to stay in the game for long or even win the game. Lifelink and speed are both very important here.
In: 4x Leyline of Sanctity, 2x Swan Song, 1x Spell Pierce
Out: 3x Spider Umbra, 1x Keen Sense, 1x Path to Exile, 2x Spirit Mantle
_________________________________________________________________________
G/W Hatebears - fair matchup
They have a hard time dealing with our creatures. Look for Path to Exile and play your fetches as early as you can as they become really bad with Aven Mindcensor. If your sideboard contains more removal side it in. Otherwise do not side anything.
_________________________________________________________________________
Infect - fair matchup
It is 50/50 chance on winning for both sides. Infect is quicker, though if you manage to kill their first few attackers, you can race them. Be as quick as possible.
In: 2x Swan Song, 1x Spell Pierce
Out: 1x Keen Sense, 2x Unflinching Courage
_________________________________________________________________________
Merfolk - fair matchup
They will soon make themselves unblockable, yet we are fast enough and we have lifelink and targeted removal. They might race the bogles, though.
In: 1x
Suppression Field
, 2x Seal of Primordium
Out: 1x Keen Sense, 2x Spider Umbra
_________________________________________________________________________
B/W Tokens - good matchup
Their only weapon against bogles is discard. If you manage to stick a hexproof creature against them, you are safe.
In: 4x Leyline of Sanctity, 2x Seal of Primordium
Out: 1x Keen Sense, 3x Path to Exile, 2x Spider Umbra
_________________________________________________________________________
Zoo - good matchup
You only have to stick an early bogle and be fast enough. Path to Exile will be handy as well as auras that grant lifelink, vigilance or first strike. Their burn spells are very unpleasant though.
In: 4x Leyline of Sanctity
Out: 1x Qasali Pridemage, 1x Keen Sense, 2x Kor Spiritdancer
_________________________________________________________________________
Scapeshift - good matchup
Their early game is weak against us, so try to use it in your advance. Be aware of the Cryptic Command lock, though.
In: 4x Leyline of Sanctity, 2x Gaddock Teeg, 2x Swan Song
Out: 1x Qasali Pridemage, 1x Keen Sense, 3x Path to Exile, 2x Spirit Mantle, 1x Spider Umbra.
(If you think they have Chalice of the Void in their sideboard, keep in the Qasali Pridemage and side in the two Seal of Primordium. Side out 2x Unflinching Courage and 1x Spider Umbra.)
_________________________________________________________________________
Soul Sisters - good matchup
Their gameplan is weak against boggles and they have almost no way how to react with the hexproof guy.
In: 2x Swan Song, 1x Spell Pierce
Out: 3x Path to Exile
_________________________________________________________________________
R/G Tron - fair matchup
They are slightly in favour. If they are on the play and play Pyroclasm on turn two, it might be deadly for us. Also Ugin kills us pretty badly.
In: 1x Stony Silence, 2x Gaddock Teeg, 1x
Suppression Field
, 1x Spell Pierce
Out: 1x Keen Sense, 2x Spirit Mantle, 2x Unflinching Courage
_________________________________________________________________________
Mono-U Tron - good matchup
Mono-U Tron is slower than R/G Tron and lacks Pyroclasm. The only problem is Chalice of the Void that is often played in the main board. Though bogles should be able to close the game earlier than the Tron is able to do something problematic.
In: 2x Gaddock Teeg, 2x Seal of Primordium, 1x
Suppression Field
Out: 2x Unflinching Courage, 1x Keen Sense, 1x Spider Umbra, 2x
Hyena Umbra
_________________________________________________________________________
8-Rack - bad matchup
First game is heavily in their favour. There is plenty of targeted discard and we quickly run out of cards. A single Smallpox can completely kill us. The same it is about Ensnaring Bridge (until we have Qasali Pridemage, but that is only one-of). After sideboarding, our chances should be much higher.
In: 4x Leyline of Sanctity, 2x Seal of Primordium
Out: 2x Spirit Mantle, 1-2x
Hyena Umbra
, 2x Spider Umbra, 1-2x Path to Exile (depends on the version of 8-Rack).
_________________________________________________________________________
Storm - good matchup
Game one is a gamble. The chances on winning are approximately 50/50. After sideboarding our chances increase.
In: 4x Leyline of Sanctity, 2x Rest in Peace
Out: 1x Keen Sense, 3x Spider Umbra, 2x Spirit Mantle
_________________________________________________________________________
U/W/R & U/W control - good matchup
They are too slow and lack responses. Their board wipes are ineffective and the targeted removal as well. They are likely to bring Spellskites and Engineered Explosives. Our only sideboard is against their sideboard. If they are likely to play enchantment board wipes, side against these.
In: 2x Seal of Primordium, 1x
Suppression Field
, 1x Stony Silence
Out: 2x Unflinching Courage, 1x Spirit Mantle, 1x
Hyena Umbra
_________________________________________________________________________
Living End - bad matchup
The matchup is good until they cascade into Living End by which the Bogles are killed and the entire board state is lost.
In: 2x Swan Song, 1x Spell Pierce
Out: 1x Qasali Pridemage, 2x Unflinching Courage
One can be asking now: Why the heck no Rest in Peace? The reason is simple. If the Living End gets countered, the Bogles will win. If not, there is the Kor Spiritdancer. After Living End resolves, if we had a Rancor on the bogle, it will now return to hand (there is no RIP). Now it is possible to rebuild quickly with the Kor Spiritdancer and the Rancor. If you do not like this plan, just side in the Rest in Peace, yet it would not be possible to rebuild.
