Artifact creatures you control have trample. At the beginning of your end step, create a 0/0 red Gremlin artifact creature token. Put X +1/+1 counters on it, where X is the number of differently named artifact tokens you control.

Target creature gets +3/+3 until end of turn.

{T}: Add {G}.

This spell costs {1} more to cast for each target beyond the first. Fireball deals X damage divided evenly, rounded down, among any number of targets.
