Well, I just wanted to keep the card from being COMPLETELY overpowered. The idea is that you're already in position to finish off your opponent by the time you play this card, except you're going to finish him off in true TTGL style: with inordinate amounts of overkill.
EpicDomo said: The last sentence is pretty much redundant.
In YuGiOh a match consists of three duels where the winner wins two of them. Hence, the effect here means you win the entire match without needing two wins.
Now just need a quick play magic card, "The Drill is my Soul", if TTGL or CTTGL are sent to the grave yard or removed from play, destroy all trap cards on the opponents field and special summon "Spiral Warrior Simon" and "Lagann" from out-of-play or the graveyard for one turn, and they may attack the opponents life points directly after being summoned. If these attacks reduce the opponents life points to 0, you win the match.
That old "Bottomless Trap Hole" card could probably stop this card long before it becomes a problem. I can't remember any recent card(s) with similar effects at the moment.
