Rain of toads and moving armies

[MaxWilson]

Target the province it's in. Magic happens before physical movement, so the only way for it to avoid the spell is to Astral Gate/Stygian Paths/etc. out (which will rarely happen) before you cast the spell. IIRC, casting order is random, so you've got a 50% chance of getting him before he teleports even if he does try this.
