So, a few things. White shouldn't really get reach just because it has archers. But if the point is that Rashka refuses to let black creatures past her, then I can dig that. In order to hammer home that concept, I also tacked on the other two common methods of black evasion.

Two, if Rashka is now going to be picky about the type of creatures she can hunt, there's no real reason to double down and maker her picky about which creatures give her the bonus.

Three, it saddens me to see the line "Whenever Rashka the Slayer blocks one or more black creatures, Rashka gets +1/+2 until end of turn." If she somehow was able to block two creatures, she should get the bonus twice. Normal Bushido makes sense on commons, but she's a rare, and should act like one.

Four, if she's going to get a bonus for each creature she blocks, she might as well get an ability that lets her block multiple creatures in odd situations. Again, Rashka won't let any black creatures get past her, so doubling down on that here makes sense.

Also, another product of "Looked fine while zoomed in. Text seems a bit small now." Consider the first two lines combined into "Rashka the slayer can block any number of black creatures, and may block black creatures with flying, intimidate and/or landwalk as if they did not have those abilities."

Also noticed, when making this card, that cards never use pronouns when referring to themselves. I kinda wanted to write "Whenever Rashka blocks, she gets...", but instead I was forced into writing her full title, then using the word 'Rashka' as if it was a pronoun, itself.

Also change to "any number of black creatures, plus one additional creature..." That wasn't my intent, but it will at least clear up confusion.

Cards do use pronouns referring to themselves, but creatures always say "it" of themselves, which is quite annoying: Karn, Silver Golem, Jareth, Leonine Titan. Planeswalkers get to use personal pronouns - Garruk Relentless says "him", as does Sarkhan the Mad and both Gideons. But that is a convention that custom card makers diverge from deliberately fairly often, especially for legends.

As for text size, the only problem is that you're trying to include the flavour text as well. 7 lines of rules text is fine, but not with flavour text too.

Removed flavor text, which is:

“Rarely be the prey so haughty as to hunt the hunter.”
—Baron Sengir

As per Alex's recommendation. Try to find another way to fit it in the set. Maybe Rashka can get a removal spell.
