My First Deck-WhiteTokens

hello!this is the first deck i built on my own :)!!!so far i was playing a mono-white soldier deck and then i decide to change it to a white token deck(i know its not that original lol).so i am new to mtg so if you see any major mistakes on the deck plz tell me so i can correct them.also i am sorry if this deck is exactly the same with any other deck but i didnt know it( although i am influenced by white token deck i saw recently here and it was a first place deck. so let me explain my thoughts about the side board i build.1 soul warden for extra life if needed.2 brave the element and 2 luminarch ascension for control deck mostly.4 devout lightcaster and 2 celestial purge(i think this is pretty obvious).2 fire walker( same here) and 2 tectonic edge if the other player plays a lot and important non land permanents.i think will work great agenst creature-lands because most of them want 3 or more lands to be activated and have any other use other than land for the player.also i build it with out ranger of eos because,as i said before,i am new in mtg and i dont have one and its really hard to find one now days lol . any tips on deck building or any corrections on this deck are welcome.thanks for viewing my deck :d.
