Little variations that you could have for bit change:
- Have each player a tri-color deck with friendly colors [W(gu)] Bant, [U(rw)] Esper, [B(br)] Grixis, [R(rg)] Jund, [G(rw)] Naya
- Have each player have a tri-color deck with enemy colors [W(bg)] Abzan, [U(rw)] Jeskai, [B(gu)] Sultai, [R(wb)] Mardu, [G(ur)]Temur
- Have each player play with the allied dual color decks [W(u)] [U(b)] [B(r)] [R(g)] [G(w)]
- Have each player play with the enemy dual color decks [W(b)] [U(r)] [B(g)] [R(w)] [G(u)]
or as we played it:
- Each player can play any deck
- if the 2 players in front of you die you win.
Which color would you rather have in the color wheel? Would you rather play a game in mono color wheel or one of the variations?
