Submerge

[Richard Cheese]

Just to make sure, there is no point between Submerge being announced and being paid for where you can remove your forest(s) from play, correct?

[Koby]

Correct, there is no opportunity for any player actions to occur during the time Submerge is announced and its costs are paid. If the opponent has a Forest in play, then Submerge may be played with its alternative casting cost.
