DZ-BT15/081 C Unrivaled Star-vader, Radon

[CONT](VC):If your opponent's front row has no rear-guards, when you would ride a "Star-vader, Chaos Breaker Dragon" from your ride deck, you can ride without discarding a card from hand.

[AUTO](RC):When this unit attacks, if you have a grade 3 or greater vanguard with "Star-vader" in its card name, this unit gets [Power]+5000 until end of that battle.
