looks like instead of splashing green to get ancient grudges probably splash black to get that falkenrath aristocrat with evasion haste and resilent with the demon to destroy artifacts and some faithless looting lets see how it works
maybe sideboarding ratchet bomb instead of slagstorm
it provides answer to hotp and geist, in the worst case ratchet gonna eat an oblivion ring but there r another threats in the board
sideboard dismember to deal with hero
and x2 arc trail more bcuz ull have answer to hotp and get card advantage
with dka out im gonna try aristocrat cuz it has evasion / haste and can survive to sweepers also wanna test tragic slip
i dont like olivia cuz in a drop 4 we want haste or something similar
those go for the throat and manic vandals r side board ^^
ir works pretty similar to this
a phoenix with +x its amazing
u have 22 lands with a cmc in 2.x maybe u can take out a land
that ancient grudge im pretty sure thats a meta call
it provides answer to hotp and geist, in the worst case ratchet gonna eat an oblivion ring but there r another threats in the board
sideboard dismember to deal with hero
and x2 arc trail more bcuz ull have answer to hotp and get card advantage
thats a thought
