Theme deck of all creatures with power/toughness 2/3. (Other people were making decks like this; I wanted one where the power and toughness weren't the same, so it'd be harder to do.)
I was going to go all creatures, but Wild Pair was just too good to skip for this janky deck.
I decided that Flip Planeswalkers and Level Up creatures (where one of the levels is 2/3) is fine for the theme.
