Valda, Seismic Impact

Valda’s first ability triggers each time an opponent draws 1 or more cards during any action phase (not just your own). When the triggered effect resolves, you will create that many Seismic Surge tokens equal to how many cards were drawn by that opponent.

If an effect results in one single event where your opponent draws 1 or more cards, Valda’s first ability will trigger only once (e.g. an effect that results in “Draw 2 cards” would trigger Valda once).

Valda’s second ability triggers at the start of your turn. Whether or not you control 3 or more Seismic Surge tokens is checked when the triggered effect resolves. If you have 3 or more Seismic Surge tokens, you will generate a continuous effect that applies to cards you own with a crush ability. When applied, those cards get dominate this turn.

Neither player receives priority during the start phase of a turn.

In the scenario where Valda successfully resolves their start of turn triggered effect, plays Leave a Dent then attacks with a Guardian weapon, the weapon attack will have Leave a Dent’s Crush ability, but not the weapon card itself. As the Guardian weapon attack is not strictly a card you own with a crush ability; it will not get dominate from Valda’s triggered effect.
