(10/14/2022) You must sacrifice exactly one creature to cast this spell
But if you have a creature with 4+ power, theres the added perk of drawing a card and discarding a card
Because that would be broken at instant speed, there is the sorcery-only break here
Thats easy
If you need an extra hand for your pingers deck, you can definitely count on Ghyrson Starn, Kelermorph
Some random cards id look into possibly adding would be Fight Rigging, Bear Umbra Mutant's Prey, Ancient Animus, Pounce, Prey Upon, Pit Fight Boxing Ring Rancor, Alpha Authority, Sticky Fingers, Fireshrieker, Whispersilk Cloak ect Most of my recommendations either give you access to -fighting (Which would trigger Wolverines +1/+1 counter trigger even when if its not your turn
