Despite the effect of transforming Battle being a triggered ability , its controller exiles the permanent and then casts it without paying the mana cost , opening up space to interact with Battle on the stack with Make Disappear, or other counterspells, or even to bounce them on the stack, with Venser, Shaper Savant and the like
you can sacrifice a creature to deal one damage to any target
Either way, the rest of spoiler season should be intense.
Whats more, that boast synergy we spoke of can be used to get a little extra mileage out of a few creatures, such as Dragonkin Berserker
I feel like this is one of the most well-realized precon decks ever out of the box, so you dont necessarily need to change 30% of the cards straight away even if I told you to jam a few games, talk with your group about the power level you want, and then decide where you want to land on the scale between AFR Set Constructed Venture Tribal and Legacy Reanimator Combo
Given that its 3 mana, I dont really like it in this version though, as your mana is often better spent elsewhere establishing or protecting the combo
