Feitiço
As criaturas que você controla ganham intimidar até o final do turno. (Cada uma dessas criaturas só pode ser bloqueada por criaturas artefato e/ou criaturas que compartilhem uma cor com ela.)
If an attacking creature has intimidate, what colors it is matters only as the defending player declares blockers. Once it’s blocked, changing its colors won’t change that.
A multicolored creature with intimidate can be blocked by any creature that shares a color with it, in addition to artifact creatures. For example, a white-blue creature with intimidate can be blocked by white creatures and/or blue creatures, no matter what other colors they are.
