MTG Keyword Rules — Comprehensive Rules Glossary

Squad is a keyword that represents two linked abilities. The first is a static ability that functions while the creature spell with squad is on the stack. The second is a triggered ability that functions when the creature with squad enters the battlefield. “Squad [cost]” means “As an additional cost to cast this spell, you may pay [cost] any number of times” and “When this creature enters, if its squad cost was paid, create a token that’s a copy of it for each time its squad cost was paid.” Paying a spell’s squad cost follows the rules for paying additional costs in rules 601.2b and 601.2f–h.

If a spell has multiple instances of squad, each is paid separately. If a permanent has multiple instances of squad, each triggers based on the payments made for that squad ability as it was cast, not based on payments for any other instance of squad.
