Here's a few of mine, in no particular order than the order they came to mind:
1) Miracle Dragon. Basically, bunch of light dragons that are hard to kill, and miracles that make you hard to kill.
2) Grabbow (mine's typically a bit different than most, but 80%+ is the same as anything you'll find on the forums)
3) Free Chaos Wyrms. Wyrms, chaos powers, shard of freedom.
4) DBH. I love denial
The first time I came across this deck in t50, I instantly fell in love with it.
5) Shard Golem. 6x Shard of Integrity, 6x novas, and add whatever shards of your choice.
6) The Blarp. Stall/deckout that Blarp made for CL.
7) 500hp EM. I like to use this one for several oracle predictions (those where I know it'll work) since 500hp EMs give more score/electrum than a normal win. I've done it both as an earth/light duo and as a rainbow. This one also blew my mind the first time I saw it in t50, mostly because I had mindgated enough stoneskins that I got a 500hp EM myself, and when I saw the electrum won, my eyes lit up with dollar signs (or whatever symbol is used for electrum)
8) The Deck. Similar to CCYB, but with lots of mods to make it bigger, better, and more fun. I've tried quite a few variants, but haven't used it recently.
9) The Serendipitous Card Advantagebow. 6x SoSe = 6x the fun!
10) Queen's Sacrifice. Nymph's tears/queens, and SoSas, and nothing else. Kill them with pillars!
