When a card has no cost but is a multicolored card I can convey that as setting color=gold but people won't know what colors it actually is unless you write it out like "Cardname is red and green" which has been replaced with the little circle. Hope I'm making sense here lol
Thanks and continue the great work.
Suspend 3— (Rather than cast this card from your hand, pay and exile it with three time counters on it. At the beginning of your upkeep, remove a time counter. When the last is removed, cast it without paying its mana cost.)
Each player exiles all creature cards from their graveyard, then sacrifices all creatures they control, then puts all cards they exiled this way onto the battlefield.
