Thanks for proving my point zitong. Despite your math being off, you just proved to yourself that IQ has a low success rate. You calculated the chance of IQ getting 1 card (you were still off though). Now, my theory is that ES is better than IQ because it doesn't waste a supporter. By your (off) math, it will usually be better to drop ES, get a certain energy, and get a supporter drop in the same turn.
Also, WHY would you put cyrus into a nonSP deck? Unless you are playing Poketurn for Luxray/Crobat, you should never put a cyrus into a nonSP deck. Once again, there are WAY BETTER supporter drops that can help you. It searches for a supporter, yes, but what if it WAS that supporter? Searching for that one energy that you need just isn't enough. Then again, I'm talking to the guy who thinks having 8 1-1 lines in a deck is a good idea...
Also Zitong, how can you NOT think that thinning the deck is a good idea? Would you rather keep your deck full of stuff? That is the basis by which most decks right now work (save for a few). Ever notice how fast decks have few cards in them? That is because they thin themselves just to get a few better draws.
