I find that jungo and junks work well, jungo boost the high life you get through winning making it hard to catch up and junks have cards like gil,rowdy,tremorh and gibson which you can save your pills for jungo so those clans work best for me, what clans work for you?
Mono Sakrohm deck. Even with Uranus haters voting to ban the card constantly, I sill have Nah boh and Trinmkkt as damage reducers. Plus Trinmkkt can be used offensively. So many other great life giving and life taking cards that even though some cards are banned, you can still make a solid deck in ELO.
I've gotten to 10 with a sentinel/ulu watu half deck in elo. Really wasn't even that great of a deck now that I think of it. None of the cards did more than 4 damage.
I like sentinel for half decks although I will say they need at least one more card to be a truly killer half deck.
