ellie-is Thanks for the feedback! Since I've been running Metallic Mimic I've noticed that its pretty much good in the beginning of a game (when not removed) and isn't the most useful when drawn mid to later. So I'm thinking of replacing it with Adaptive Automaton since I still want some kind of lord for the deck and I can still pull it out with Collected Company. I hope cats get a proper lord since the only one is the high cost Caracal.

Mint0055 Thanks for the sideboard help. I will be working on getting some of those suggestions! I've also added in 2 Ghost Quarters. So I'm looking forward to seeing how my modifications change my future matches.

Ooh, Cats. I helped build a tribal cat deck with my brother, but in Naya colors (partly for Wild Nacatl). At least in Selesnya colors, though, you still have a lot of cat-tastic options.

Some suggestions:

• Loam Lion comes down fast as a 2/3 with a Temple Garden in play, but, if you go with Loam Lion, you need four Temple Gardens. I would run more Temple Gardens in lieu of the Sunpetal Groves, though (or even Canopy Vista!), because having both of the land types is somewhat useful here.
• More Qasali Ambushers are a good option if you're running more dual lands, especially since they trade with/kill a lot of fast threats and are my favorite price of all (free).
• Run more Qasali Pridemages if possible, especially with Lantern decks everywhere.
• In the sideboard, I might consider Thorn of Amethyst to deal with creature-light decks and Rest in Peace instead of the Relic of Progenitus. You can also use Angel's Grace and Dawn Charm as a possibility to deal with insta-kills (and I'd think Dawn Charm's better than Druid's Deliverance).
• While I fully approve of Stony Silence, maybe a singleton Fracturing Gust would be worthwhile to deal with affinity and lantern: it kills all artifacts for a low price, even though it costs five mana (but, against lantern, many of the super-troublesome artifacts don't require the use of activated abilities to screw things up. Alternately, you have Kataki, War's Wage, which kinda looks cat-like...
• Ajani, Caller of the Pride is a good planeswalker, but you need to be ahead to make him work. I prefer Elspeth, Knight-Errant, as she buffs your attacking kitties and makes guys to protect you if your board is empty. (Plus, she might also fit the theme...(?))

You need to get rid of your windswepth heath. You cant play leonin arbiter in a deck with fetchlands.

fluffyeel you shouldnt play a five cmc spell in a deck with 21 lands so gust is defenitely not an option.

You dont need to be ahead for ajani to work you need one creature on the board to make him work and elspeth simply costs one mana more to cast and you dont want that many 4 drops in your deck

lukas96 Currently just running test matches with arbiter and haven't run into the fetch issue but I know I will once I keep playing. I will most likely replace the lands with 2 more Unclaimed Territory and possibly 2 Razorverge Thickets. Still trying to decide the lands to switch out with.

Yeah i think that would be ok

You shouldnt replace mimic with automaton. You already have a lot of three drops and swaping a two for a three drop would not be good for your curve.

Mimics buff with +1+1 coubters is permanent and autimatins buff is gone if it dies so in a vacuum it might be better than mimic but if you play againat a real opponent its much worse
