If your opponent controls a card and you control no cards, you can Normal Summon this card without Tributing. If this card attacks an opponent's monster, as long as you control no Spell/Trap Cards, your opponent cannot activate any Spell/Trap Cards until the end of the Damage Step.
Treeborn Frog’s activation condition also requires you to control no Spell/Trap cards so that it can be Special Summoned from your Graveyard to the Field. As a result, you may be Tribute Summoning Hammer Bounzer instead.
You need more fire typ monsters in a hazy deck to use their effects the correct way. I Don't think Bounzer and Thunder Vassal will see many play in that deck. You also give you opponent a defensive token with Vassals effect but you want to OTK and that won't be possible if he already has 1-2 monsters on the field.
