Haste

Whenever another creature you control with base power 1 enters, it gains haste until end of turn.

Whenever another creature you control enters, if it wasn't cast, put a +1/+1 counter on Rapid Augmenter and Rapid Augmenter can't be blocked this turn.

Cast this spell only before blockers are declared.

Target creature gains first strike until end of turn. If it doesn't have rampage, that creature gains rampage 2 until end of turn. (Whenever the creature becomes blocked, it gets +2/+2 until end of turn for each creature blocking it beyond the first.)

Whenever you crank Rapid Prototyper, create an X/X colorless Construct artifact creature token, where X is the number of artifacts you control.
