Because you can ' t cast anything else , there ' s no way to forget that you need to pay for it , and from there it should be trivial enough to remember what you did pay for it . I don ' t follow your logic here at all . The problem starts with players not remembering whether or not they paid the full cost in the first place . It ' s not like players will find themselves unable to put creatures from their hand onto the battlefield on their next turn . And remembering which of your lands were tapped for how much mana a turn or more ago is not at all a trivial thing . <| sep |> The defense can ' t stop the GOAT Tolzien <| sep |> Go out the back door and find some nice grass to piss on <| sep |> Lol , I actually had a similiar situation . Kanji is okay with me , but its katakana that I struggle with . I don ' t read use write it enough . While Kanji is a bit more frequent . I had to write my address in Kanji then katakana so I can pay my bill by cash card . I messed up twice , asked the cute girl to help me because I was a useless gaijin . She said no . Now I got her asking me everyday I see her 5 days before due date to remind me to pay the bill soon . Today is that day .
