Now this is interesting.

If I use Giga Drill Break, then I use Drill Warrior's ability, I'd have one attack saying I can't and another saying I can. Interesting.

Very interasting.

Drill Rapture is like a weird Relinquished. I like these. Nice work.

[Lunar Origins]

Well it seems I've found another Gurren Lagan fan. Interesting cards, although I don't have muc more to comment on. I'd like to see some more of these iactually as they are rather good.
