The...Limited?!

Let's take a look at all the wonderful cards that we can now (only) use one of!

BLACK WHIRLWIND:
The BW engine was still REALLY strong at two. Watering it down to one perhaps keeps it balanced enough that other aspects of the deck don't need to be bothered with. Personally, getting single whirlwinded instead of double whirlwinded still hurts. But this is good to see!
Verdict: Good Call!

DARK HOLE:
Oh gosh why. Why oh why. You kick storm and bring back this? Is that the logic? Anyways, you better start packing more starlight roads.
Verdict: WTQ

INFERNITY LAUNCHER:
Uh...I guess this was just a necessary thing to do to again, water down the simple lovin combos of the fast decks. Will infernity feel it? Of course.
Verdict: Good Call! (but we saw it comin)

MONSTER REBORN:
Ooooo I guess you like it when I take your monster ooh ooh. There's gonna be many tears over topdecks of this.
Verdict: WTQ

ROYAL OPPRESSION:
Now this one's a little different. Yes, it was becoming a nuisance, having been splashed into almost every playable deck (main/side). Was a limit necessary? Perhaps not. Will it encourage new strategies? I hope so. No more banking on your ROs to lock things down! Of course, one can still do it in many cases.
Verdict: I don't care.

This would probably be better if I discussed things with someone else. Oh well!
