NFT Play-to-earn DAO tokenomics

We're building a NFT trading card play-to-earn game. L2 eth... probably avalanche chain. We're looking for someone with experience developing the tokenomic model. For example: 1. We'll be selling NFTs - Avatar cards of various rarity/power - Soldier cards of various rarity/power - Powerup cards of various rarity/power - Gas fees for low-level item purchases like these are paid by the user directly while they pay in chain-coin 2. We'll have a token(erc20) that fuels transactions in the game - This token can be purchased for AVA/Chain-coin - We will give a small amount of this token to new players to get started (play for free) - Limit 1 new free character per wallet address - Tokens given for free are not tradeable/stakeable (user must have SPENT more than the initial free alotment before their account becomes able to trade/stake tokens) - Accounts that do not exceed expenditure of initial free alotment (they will receive more 'free' tokens for winning/doing things but these wont count) will start to be taxed 10(?) tokens per day of inactivity 3. When a user does something in the game the saves state (win a battle, create a tournament) the transaction cost to update the chain (which we'd have to pay in avax/chain-coin) would be paid by the game's treasury. - We'd charge the user in our ERC20 tokens for taking the action. - The rate we charge would be determined by ???? (we could potentially have a 'current gas fee' value in the contract that is periodically updated by a an oracle... then based the token fee for each action on the value of our token vs value of avax/chain-coin and the current gas rate... plus some small amount to add to the treasury where we pull prizes from for other players/create yield for stakers --- or do you see this working entirely different?
