4, : Play a ready 3 Sprite unit token with [Temporary]. This ability costs 1 less for each friendly unit with [Temporary].

When you play a token unit, give me +1 this turn.
Your token units have [Tank]. (They must be assigned combat damage first.)

[Accelerate] (You may pay 1 as an additional cost to have me enter ready.)
When I move from a location, play a 3 Sprite unit token with [Temporary] there. (Kill it at the start of its controller's Beginning Phase, before scoring.)

[Reaction] (Play any time, even before spells and abilities resolve.)
Counter a spell. Its controller can't play spells this turn.
