You are thinking of sheer numbers only but does your deck has a theme/strategy otherwise?
Viral Drake could be useful as you need only 10 poison counters to win the game. Faerie Artisans mean you get twice as many creatures each turns with doubl enter the battlefield effects. Selecting a card as Toothy, Imaginary friend mean you will have to apply the Legendary rule, so no matter how many cards you draw thanks for Toothy, the copy get as many +1/+1 counter. Perplexing Chimera allow you to respond to your own Perplexing Chimera trigger, picking the spell they wanted to cast so that their own Perplexing Chimera trigger effect fizzle.
