More of a casual deck, using the potentially very strong combo of:
If one of them gets a counter, the other one does as well, so they each trigger each other and – boom – they are infinitely big. Now you just have to use that somehow to your advantage.
What we need is ways to trigger them, ways to keep them alive, ways to dig for them, ways to keep you alive long enough and ways to give them haste. Easy enough? No.
Maybe you could accidentally actually win games with this one. You never know. It does work hard not to.
