Just to follow up, I went for the multicolored and the poison one, and it seemed that he liked both about the same but he was probably winning more with the poison one more, so any money that he won I used to start upgrading his frogs first, then his scorpions. After that, it seemed he could even beat like the top 50 type people more often than he lost! so from that he started winning shards and I put those in. Any idea how to improve further, assuming I would have all the rare cards I would need to make it? Here's the deck as it stands now (I added more pendulums instead of pillars in order to compensate for increased cost of deadly poison)

Thanks a bunch, Jimmy really appreciates it! The lifetime stats on the account (including my fumbling around) are 1552 wins, 611 losses !
