Thats insane amounts of card draw, and on a respectably costed three mana 4/4 with crew 3, youll be able to achieve this very easily
For example, I cast [c]Adaptive Shimmerer[/c] during my opponents end step
We had talked about adding in toys and other little items but instead went for the big round flowers that might read as balls of yarn and little mice peaking around
Though she has a cost of 7 Ink, Clarabelle is a Floodborn character, which means that she has the Shift keyword, allowing her to be played directly on top of another Clarabelle card, for a reduced cost (in a manner reminiscent of how evolving works in Pokemon)
As far as card recommendations go, Id suggest running the likes of Essence Pulse, Blossoming Bogbeast, and Mortality Spear
