I don't think the gamecards will work as they only renew existing accounts; you need a cdkey(gamecard keys are diff I figure) and used to create a new account; if you already have 2 accounts(and they're yours/same name/billing info/email; if not you risk them being banned for acct sharing) yeah a gamecard will work, all the chars are on different accounts since you can only log on 1 char per account at a time.

And nothin wrong with using non-Keyclone alternatives, I started with AHK cuz I was cheap too ;) Plus it's better to use the free stuff while you learn then move up later once you're sure you'll be committed to it; I don't regret upgrading to Keyclone, makes things aloooooooooot easier once I was sure I would be boxing for a long time lol
