Good Assassin in Conjuration?

[TigerBlood]

I don't understand. Mind Burn and Soul Slay are both MR negates. Of these two spells, only Soul Slay threatens a Harvester.

Granted, I have been in a game where an S4 mage somehow took out an MR30 Wyrm with one cast of Soul Slay, but I have also seen some MR16 units very persistantly resist spells cast by a mage equipped with a penetration booster. MR18 is pretty good. It can easily be improved upon.

As for distinctions on the order of assasination and casting, that is irrelevant. The moment you use an assassin, it's location is known. The moment a Harvester moves into a province and begins diseasing units, it's location is known. A black heart simply gives the Harvester something to do while it is camping on an occupied province. Considering they can thug fairly effectively, the more conventional counter to assassination, patrolling, is potentially less of an issue. If I can coerce an opponent into wasting mage turns trying to root out an obvious threat, rather than relying on mundane patrollers, then hooray for me.
