Looking for help on my Xavier deck

{"ops":[{"insert":"Overall, your deck right now is kinda slow until you get the full \"combo\" and you suddenly get a ton of value. smooth out your deck to make it more consistent, and you should do great! I added some specific tips below.\n\n1) I would put in some more mana rocks. (signets, talismans). You have 27 cards 4 mana or higher, which the mana rocks can ramp into. I normally have around 7-10 mana rocks, and right now you have 3 I believe.\n\n2) You need some more removal. I saw 2-3 single target removal spells, which just isn't enough. If the opponent plays a solemnity for example (I don't know why they would they're just weird I guess) you probably can't remove it, and now your gameplan is shut down.\n\n3) Put in some more card draw that DOESN'T need you to have anything else. ponder, preordain, phyrexian arena, etc. In my playtests, I ended up running low on cards or having disjointed pieces that don't work together. Cards like parallel lives and elemental bond can work well with the deck, but only if you can consistently get the upside from them.\n\n4) simplify the game plan. The game plan is to have (a) a counter and (b) a creature token. Try removing cards that do not achieve this goal. You should activate your game plan the majority of games. Right now, in my play tests, it seems like the problem isn't how the deck works when its working, but how it doesn't do it consistently. Put in some more creatures (maybe? my playtests seemed to be low on good creatures) and probably some creatures that enter with counters.\n"}]}

{"ops":[{"insert":"I'd consider cards like "},{"insert":{"card-link":"Grismold, the Dreadsower"}},{"insert":", "},{"insert":{"card-link":"Forgotten Ancient"}},{"insert":", "},{"insert":{"card-link":"Sarulf, Realm Eater"}},{"insert":", or "},{"insert":{"card-link":"Awakening Zone"}},{"insert":" that get counters and/or make tokens for free.

I also see very little interaction; would suggest adding more. Cheers!\n"}]}

{"ops":[{"insert":{"card-link":"Idol of Oblivion"}},{"insert":" is good both in the early game as a cheap repeatable way to draw cards, but also late-game as a fantastic token to start populating.\n"},{"insert":{"card-link":"Ledger Shredder"}},{"insert":" is a nice early-game value piece, but I don't really see the synergy with the rest of the deck.\n"},{"insert":{"card-link":"Mirror Box"}},{"insert":" or "},{"insert":{"card-link":"Spark Double"}},{"insert":" let you start using your many clone effects to duplicate Xavier, which can get out of hand very quickly.\nWe can use the cost of his populate ability that removes counters from permanents we control to get upside with cards like "},{"insert":{"card-link":"Binding the Old Gods"}},{"insert":" and "},{"insert":{"card-link":"The Cruelty of Gix"}},{"insert":" to get some insane recursive value out of our sagas by removing lore counters.\n\nHope I gave you some new ideas!\n"}]}
