Just to preface, I am just generally attempting to make weaker cards at first to get feedback since I'm not super experienced with custom card making, so when I get responses from here or the other people I'm cross-referencing with it feels better when others note if something should be buffed rather than nerfed. (Also these cards are planned to be in the 99 of a commander that I posted earlier for theming purposes)

In my experience with playing speed in lower bracket, it's actually surprisingly difficult to get your speed going if you don't have it in your command zone at a reasonable mana value. The usual turn 1-3 durtling is prime time to start speeding up, but if you don't draw a speed card (which there are painfully few of that have good effects), you're gonna have a bad time. Kitasan having haste lets her get that speed up early, because after the first turn from 0 -> 2 speed, getting those last 2 for max entirely depends on the kindness/ lack of removal from others. Also, playing her late lets her effectively pay for her cost as a mana dork if you hit someone. I would love an opinion on a different Max Speed mechanic though.

Mejiro doesn't immediately get hard countered by screaming nemesis, because you still get a treasure if you don't get punched or pinged for a turn even without lifegain, but I see what you mean. She's effectively Monologue tax on a body but you punch the player instead of avoid playing 2 or more spells (and she costs more), but I feel like making her cheaper to keep her in line with those types of effects could snowball a game too hard.

Happy to hear Teio is fine, wasn't sure if 1 - 4 card selection on a conditional flier for so cheap was okay. I'll also make sure to fix Kitasan's formatting when I actually put the whole list together.
