This is an annoying deck that works fairly well in platinum division. The idea is to prevent your opponent from keeping stuff on the battlefield and/or neutralise it.
Do not be afraid to bounce your own creatures. A weirdly powerful combo is
Shipwreck Dowser/
Sublime Epiphany which allows you to copy the dowser and return the Epiphany from the Graveyard at a cost of six mana per turn. I don't think this should work in actual MtG, but works on the Arena. Dowser also works grossly well with Thassa, Deep Dweller.
The strength of this deck is that opponents are often better prepared to deal with you killing their stuff than bouncing or turning them into animals. Also, gaining card advantage is another strength of this deck. This deck is weak against turbo-mill and instant sorcery to the face burn.
