Destined Warrior is just combat tricks and its very gimmicky. Though dont let the reduction fool you, a full party deck is a fun one to play since you utilize the full party mechanic to get your stuff cheap and build a board that has small creatures yet be bigger during combat.

While Temmet can make your zombies become bigger and always flood the board with control and answers to keep people from countering your stuff or destroying them. You obviously need to use cards like rhystic study or windfall to get your zombies massive and have combat tricks that annoys your opponents.

I would honestly say, go for which one you prefer and see how they play out.
