[VGE-V-EB01] The Destructive Roar
Ravenous Dragon, Megarex
[AUTO](VC/RC):When it attacks a vanguard, [Cost][retire another rear-guard], and draw a card. If this unit is on (RC), [Cost][Counter-Blast 1], put the top card of your deck face down as an equip gauge for this unit, and it gets [Power] +5000 until end of that battle for each gauge equipped to this unit.
That prey was satisfying.
