[AUTO](VC)[Counterblast 1 & Send three rearguards with 'Conquerer' in their card name to the soul]: When this unit attacks a vanguard, if this unit is in Legion and there will be 8 or more cards in the soul by the time the cost is paid, you may pay the cost. If you do, this unit gains [Power]+10000/[Critical]+1 until the end of the turn.

Just saying I've never heard of a unit's skill which could predict the future, maybe you could try:

[AUTO](VC): [Counter Blast (1) & Choose three of your rear-guards with "Conquerer" in its card name, and put them in your soul] When this unit attacks a vanguard, if this unit is in Legion, you may pay the cost. If you do, if you have eight or more cards in our soul, this unit gets [Power]+10000/[Critical]+1, until end of turn.

Really, it just relies on the user not being an idiot ._.
