FantasyArena.TotalSupply(uint256) (#218-220) should emit an event for:
- maxSellOutNum = num (#219)
FantasyArena.Burnliquidity(uint256) (#221-223) should emit an event for:
- maxSellToken = num * 1000000000000000 ** uint256(decimals) (#222)
Emit an event for critical parameter changes.

FantasyArena.transfer(address,uint256) (#110-133) compares to a boolean constant:
-require(bool)(blackLists[from] == false && blackLists[_to] == false) (#115)
FantasyArena.transferFrom(address,address,uint256) (#167-194) compares to a boolean constant:
-require(bool)(blackLists[from] == false && blackLists[_to] == false) (#173)
Remove the equality to the boolean constant.

Pragma version^0.6.0 (#8) allows old versions
Deploy with any of the following Solidity versions: 0.5.16 - 0.5.17, 0.6.11 - 0.6.12, 0.7.5 - 0.7.6 Use a simple pragma version that allows any of these versions. Consider using the latest version of Solidity for testing.

Low level call in Address.sendValue(address,uint256) (#47-51):
- (success) = recipient.call{value: amount}() (#49)
Low level call in Address._functionCallWithValue(address,bytes,uint256,string) (#65-80):
- (success,returndata) = target.call{value: weiValue}(data) (#67)
Avoid low-level calls. Check the call success. If the call is meant for a contract, check for code existence
