Summary Judgment

Activated abilities of artifacts your opponents control can't be activated. +1: Until your next turn, up to one target noncreature artifact becomes an artifact creature with power and toughness each equal to its mana value. −2: You may reveal an artifact card you own from outside the game or choose a face-up artifact card you own in exile. Put that card into your hand.

Whenever a creature you control attacks alone, it gets +X/+X until end of turn, where X is the number of creatures you control.

This creature has vigilance as long as you control a Gate.

Target creature gets +2/+2 until end of turn. Addendum — If you cast this spell during your main phase, that creature gains flying until end of turn.
