SquadSquad 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 replacement effect applies to a token entering the battlefield, that effect applies after considering any continuous effects that will modify the characteristics of that token.
Previously, an effect that created tokens instructed a player to “put [those tokens] onto the battlefield.” Cards that were printed with that text have received errata in the Oracle card reference so they now “create” those tokens. (CR 701.7) that many tokens that are copies of it.)
