Mixed in 2HG — symmetrical lock piece, but team anthem.
- +9Symmetrical lock piece
Stax and tax effects tax two opponents for the price of one, while your team plans around them together.
- −4Team anthem
Anthems only pump creatures you control — your teammate's board is untouched, so they're worse than they look.
Ratings start at a neutral 50 and are adjusted by rules derived from 2HG's structure — shared 60 life, shared turns, two opponents. They'll be recalibrated against real play rates once teams start submitting decklists.
