Many of the cards that create tokens create powerful or evasive ones, and with creatures making up the majority of the deck, you'll be dwindling life totals down all throughout
How many copies of a card get played depends on several factors, including casting cost, color requirements, available color fixing in the format, whether the card is legendary and whether multiple copies are redundant if played into the current board state
With Greninja's ability, players can deal 20 damage to an opponent's Pokmon each turn, and players can set up multiple copies to do 40 damage each turn
My favorite card might be Minion Reflector
