There are ERC20 tokens that may make certain customizations to their ERC20 contracts.
One type of these tokens is deflationary tokens that charge a certain fee for every transfer() or transferFrom().
Others are rebasing tokens that increase in value over time like Aaves aTokens (balanceOf changes over time).
The PrizePool._depositTo() function will try to supply more _amount than was actually transferred.
The tx will revert and these tokens cannot be used.
One possible mitigation is to measure the asset change right before and after the asset-transferring routines
