Talk:Upgrade/@comment-190.100.172.149-20150209173938

hello guys, I have Starscream (2) trans-scanned and Starscream (1) Alt mode, also Skywarp (2) and (1), Shokwave (2) and (1) and Thundercracker (2) and (1). My question is if it is possible to upgrade a (2) card with a (1) card and if it is worth it, i mean if Starscream (2) will be more powerfull upgrading him with Stascream (1) or if I just keep them both separately. Thanks.
