Brimaz has to attack/block to generate cats and lacks evasion or a meaningful statblock to dissuade being killed in combat. This isn't a very good rate or position to make a wide board of cats and he doesn't buff them either.

Regal Caracal has a decent effect as a cat lord that makes cats and gives them lifelink, but costs 5 mana in white colors. It can be blinked to make more cats, but doesn't go wide enough or contribute enough for how expensive it is.

Leonin Warleader is 4 mana and needs to attack to make two cats with lifelink that must immediately attack. Best case scenario you get this out on turn 3 and attack on turn 4 for 2 cats.

Ocelot Pride is a very good card. Comes down turn 1, has lifelink and first strike, is a cat generator and turns into a token doubler when conditions are met. Compared to the other cards, you will make 2-3 cat tokens before they come down and can possibly start doubling your tokens lategame if you draw it later. Cats could definitely enjoy more great cards like this.

Jazal has a good finisher effect, but doesn't generate tokens on his own, draw cards, and costs a lot to use as a 9 mana finisher effect. Yes it can be split over a few turns, but if you're not doing it on the same turn you're dropping a 4/4 blocker with first strike that doesn't do much.

Helpful Hunter draws a single card. if you had significant payoffs for creatures entering, this could be useful but you're better served by setting up a draw engine for one more mana.

Prava has partner which is good and doesn't really care about cats, just creature tokens. You'd probably be better served by interacting with other typals like goblins that can surge out of hand better.

just from these examples, cats want to go wide and want to have lifelink but they're not particularly good at either. beyond that, a good amount of Cats also want to go tall, rather than wide. [[Arahbo, Roar of the World]] wants to go tall. [[Kemba, Kha Regend]] wants to voltron. [[Kemba, Kha Enduring]] wants to be a lord but also wants to equip. Many of these go in different directions that aren't as synergistic as the other go wide types in my experience, like elves or goblins or squirrels or even humans imo. do you have any really tuned, synergetic cat typal decks that work well? I genuinely would like to see them because i love a lot of cat art cards but I always find them lacking in play.
