Emry, Lurker of the Loch
is an absolute beast in this deck. It can support our infinite turns combo by you tapping and then sac'ing a
Coretapper
(for 3 charge counters on scepter) and then tapping
Emry, Lurker of the Loch
to return coretapper on the same turn (before you go to your extra turn).. And when you extry turn arrives, you can repeat the process for infinite turns.
Emry works great in this deck because you'll almost ALWAYS get to cast him for a single blue mana (due to all of the artifacts) and his 4 cards off the deck-to-graveyard works in our favor to dig for combo pieces and then recover them next turn.
Other cards you can sync well with
Emry, Lurker of the Loch
are:
Mishra's Bauble
-- for free extra draws until you assemble your core combos
Mox Opal
to replace an already tapped for mana mox opal with an untapped one for a free mana (due to legendary rule, the old one is replaced)
1x Engineered Explosives (MMA) (sideboard) for an EE every turn.
Darksteel Citadel
just incase you end up with on in your graveyard with Emry's ability
Recursion of core combo pieces due to removal like
Magistrate's Scepter
,
Darksteel Reactor
,
Ensnaring Bridge
,
Surge Node
, etc.
