GOBLIN TRIBAL with [Zada, Hedron Grinder]
I have made a lot of changes to this deck.
Goblin Tribal Is underrated
Lots of synergy between goblins here.
I have roughly a 70% win rate with this deck so far on Arena in Explorer format.
Zada, Hedron Grinder is the hordemaster here and the top of the Mana curve facilitates big sweeps with its ability to copy my buff spells for all other goblins.
Skirk Prospector provides a means to generate addition mana with the sacrifice of a goblin and Den of the Bugbear, Goblin Instigator, Battle Cry Goblin all provide me with extra goblins to attack with or potentially sack for mana, while Battle Cry Goblin will often give them +1 and haste.
Goblin Warchief enables me to play goblins much cheaper while giving them all haste
With Goblin Instigator + Goblin Warchief + Skirk Prospector
can ramp as It costs 1 Mana for 2 Goblin which sack for combined 2 Mana.
Conspicuous Snoop, can make use of all your Mana, and help provide Card advantage, especially when your hand is empty, to continue the stream of goblins to the battlefield.
Rundvelt Hordemaster who gives all your other goblins +1+1 can also provide a form of card advantage, though not as good as The former
Witch's Mark + Zada, Hedron Grinder
allows me to draw a ton of cards, while also giving everything +1+1 and the ability to sack all my goblins to do damage to make my opponents lose 1 life per goblin that dies with Skirk Prospector + Witch's Mark + Zada, Hedron Grinder
because of the wicked role's effect
Alternatively the opponent can be made to lose lots of life from the enchantments when Monstrous Rage + Zada, Hedron Grinder
replaces the wicked role tokens from Witch's Mark with monster role tokens.
Monstrous Rage + Zada, Hedron Grinder
is a huge Game ending move to give all.my creatures +2 +0 until end of ture but also gives each of my creatures an enchantment token that gives +1+1 and Trample Turning my side of the field into a rain of death.
