[AUTO](VC):[Counter Blast (1)] When this unit Legion, you may pay the cost. If you do, choose one of your opponent's rear-guards, and retire all of your opponent's rear-guards in the same column as that unit.
[AUTO](VC):[Soul Blast (1)] When this unit attacks a vanguard, you may pay the cost. If you do, this unit gets [Power]+3000 until end of battle.
You must be thinking "he can't be serious, can he?"
To answer that, yes, yes I am serious, but not for the reasons you may think.
Sure COTW is meant to praise good cards or units which have a particular appeal, but there is none of that here.
In a booster set with 10 RRR's and 3 to a box, with no matches, if you open a box and this is one of your RRR cards- your heart just sank thinking about it didn't it?
This unit is the Desperate Dragon of Blazing Perdition. The one RRR no one wants to pull, but at least Revenger, Desperate Dragon could be used as a cheap boss for a budget deck. Meanwhile this doesn't even do that. Sure it can retire a column cheaply, but it can only do so once, when it performs legion. By this point you may as well just be using a Vanilla Legion and just aiming for that additional power to drive you above 31000 (into 5 stages) when boosted.
And in case you were wondering if this thing could possibly be saved by it's mate-
[AUTO]:[Counter Blast (1)] When this card is placed on (RC), if you have a vanguard with "Perdition" in its card name, you may pay the cost. If you do, choose one of your opponent's rear-guards in the same column as this unit, and retire it.
It really can't...
You know it's bad when your mate, as a stand alone unit can be considered better than yourself. Despite doing the same thing, one time skill, and vanilla the rest of the time. Except this is excusable with rear support, not so much when you're supposed to be leading the charge.
Perdition Dragon, Pain Laser Dragon should have been a single Rare at best. The ONLY reason I can think of as to why he is RRR is so he has a higher rarity than his mate. This does not strike me as a valid justification when your mate is better than you are. Heck, Perdition Dragon, Menace Laser Dragon is more deserving of the RRR spot than Perdition Dragon, Pain Laser Dragon.
