With so many powerful game-winning triggers you must stop, your only way to shut off Brago Beats, is to remove its ability to force hits with things like Rogue's Passage or Steel of the Godhead (or shut off combat damage with something like a Fog effect)
The goal is to play creatures that do something when we draw our second card for the turn and then draw a bunch of cards to trigger our creatures, hopefully overwhelming our opponent with grindy card-draw value
Anyone who has seen it in play will be able to fill you in: making a Goblin every turn, immediately giving it a +1/+1 counter, and then swinging in with it stacks up some damage pretty darn quick
It's slow on its own, but once you add proliferate or counter doubling, it charges much faster
Depending on how much mana you pump into this spell, you could dig pretty deep into your library and set yourself up for a great next turn
For now, this Venusaur earns its flowers on the back of the best floral design in the set
