mtg bonus card burnt offering MTGNexus Burnt Offering was my SL

It costs one more mana than Heros Downfall but will take out 98% of the things that spell will while also giving you scry 2, which is close in power level to drawing a card

Carmen does cost five, though, so the rest of your deck should be filled with equal amounts of recursion (Sevinnes Reclamation et al), ramp (Ancient Tomb, Sword of the Animist) and evasive bodies that can also grow tall (Voldaren Bloodcaster, Liberator, Urzas Battlethopter, Serra Ascendant)

Some immediate creatures you could bring back include Kroxa, Titan of Death's Hunger, and Blood Artists for maximum value

While the design of this card is surely elegant, the ability for it to pop off with any number of cards that plant +1/+1 counters on it makes it somewhat problematic
