Creature â Human Shaman Ally
Cohort â€” , Tap an untapped Ally you control: Discard a card. If you do, draw a card.3/2
To activate a cohort ability, the Ally with that ability must have been under your control continuously since the beginning of your most recent turn. Informally, it canâ€™t have â€œsummoning sickness.â€ However, the other Ally you tap can be one that just came under your control. (Note that tapping the second Ally doesnâ€™t use [the tap symbol].)
Discarding a card is part of the abilityâ€™s effect and isnâ€™t optional. As the cohort ability resolves, if you have a card in your hand, you must discard one, even if the card you may have wanted to discard as you activated the ability is no longer in your hand.
