Cogwork Tracker

If the noted player isn't in the game, Cogwork Tracker's last ability won't do anything, although it must still attack each turn if able. This is also true if there is no noted player because Cogwork Tracker was the first card drafted from a booster pack.

If, during your declare attackers step, Cogwork Tracker is tapped, is affected by a spell or ability that says it can't attack, or hasn't been under your control continuously since the turn began (and doesn't have haste), then it doesn't attack. If there's a cost associated with having a creature attack, you're not forced to pay that cost, so it doesn't have to attack in that case either.

If the last ability doesn't apply, you choose which player or planeswalker Cogwork Tracker attacks.
