War of the Spark

[Megadeus]

This set is rock solid.



Dreadhorde Arcanist

Trample
Whenever Dreadhorde Arcanist attacks, you may cast target instant or sorcery card with converted mana cost less than or equal to Dreadhorde Arcanist's power from your graveyard without paying its mana cost. If that card would be put into your graveyard this turn, exile it instead."

EDIT: And yes, this works with Ancestral Vision/free spells.

Sorry for double post, but become Immense into cast become Immense again is actually pretty nasty
