I have been wracking my brain, trying to come up with interesting ways to use Piracy.
Until end of turn, you may tap lands you don't control for mana. Spend this mana only to cast spells.
With Sen Triplets in play, target opponent can't activate abilities of their permanents:
This turn, that player can’t cast spells or activate abilities and plays with their hand revealed.
Since tapping a land for mana is an activated ability (activation cost is
T:), then does this mean that the opponent can't tap their lands?
If so, can I then cast Piracy to use their lands to generate mana in addition to my own, safe in the knowledge that when I pass priority, the opponent won't just tap their lands?
Bonus: Further, if I have Strionic Resonator in play, then could I do so to multiple opponents in a multiplayer game, by copying the Triplets' triggered ability?
