Overwhelming Tokens

this is a deck that ive been running for a few months at my local fnm and a few bigger tournaments with a fairly good success rate. the first few weeks i was constantly 4-0 and finishing in the top 2 then for no reason the deck couldnt seem to beat the same ones ive played previously. im looking to make some changes and any thoughts would definitely be appreciated. mentor is mostly in the deck due to the card advantage that ill usually manage to utilize until late game then hes more of a hindrance than anything. i do tend to take a fair amount of damage early, usually between 4-8 damage then im able to regain all the life and then some.
