This variant of Handbuff Paladin uses Adaptive Amalgams, due to the Amalgams costing 1, having 1/2 for starting stats, retaining all handbuff stats and returning to the deck upon death — to be played again with their buffs when drawn and played again. While there are counters to them, Amalgams allow the Handbuff player to pile handbuffs on them and returning them to play multiple times for only 1 mana each time.
I also added Overlord Runthak due him handbuffing minions in the hand for +1/+1 each time he attacks — which is quite a bonus if he himself gets juiced enough by handbuffs and manages to attack several times.
The Zilliax has the Power Module and Twin Module. (Doubles stats each turn, and summons an extra copy.)
