Going over the monsters and the cards in generally. It appears that the archetypes theme seems to be all over the place. It is a battle orientated archetype yet it has low stats. Also some of the effects such as spell, the promoter and all of the xyz monsters bar dragon seem to be a little too strong in what they are attempting to do. Perhaps reduce the overall search and the potency of some of the effects. While also increasing the attack of the monsters. Might seem to work.

Otherwise I cannot accept this archetype as it currently is.
