Creature â Dwarf Artificer
At the beginning of combat on your turn, if you control an artifact, Toolcraft Exemplar gets +2/+1 until end of turn. If you control three or more artifacts, it also gains first strike until end of turn.1/1
Whether or not you control three or more artifacts is checked only as the triggered ability resolves.
If you control no artifacts as your combat phase begins, Toolcraft Exemplarâ€™s triggered ability doesnâ€™t trigger at all. If you control no artifacts as the triggered ability resolves, it has no effect.
