(If you ride this unit, you get one Imaginary Gift:Protect!) [CONT](VC/RC):During your turn, if your drop zone has ten or more cards, this unit gets [Power]+10000. [ACT](Drop Zone):COST[Counter Blast (2)], call this card to (RC). If your vanguard is grade 2 or greater, and it was not placed during this turn, you may ride it as [Stand] instead of calling it.
This will end when you die? I have never heard about such a rule.
