well I have tryed jmizzels small deck more extensivly. I´ts nice to play and fast. To many problems arise with these kind of decks though. The winning % goes down. Simply not as good as the 40-45 card decks.
Rainbow is actually easy if not for the dumb problem of miracle wich screwed me over three times. thers no space for mistakes with these decks and you can easily get screwed over by most gods if they get a good draw or you a bad one. Getting a bad draw yourself is almost impossible aside of having ffq druid or the pulv at the end. Worst thing is running out of cards. Happens every now and thene because you have minimal offense, and drawing those needed cards late can screw you over bigtime.
I made a small change later on .....6 SD are not needed actually. they get in the way more than help. I dropped one and used a few diffrent cards in it´s place. Bonewall was nice but it only helps minimal and you need it early to be affectiv. The other two I tryed are eternity and anubis. Those two cards I used (only one at a time),improved Jimizzels deck by leaps. At least for me it did. Nother card I did not use but could help, is purify.
Gonna go back to my old deck, wich at 46 cards(3 shards) simply gaines points at a faster rate for me. But still a great deck, defnitly worth playing it.
