Set Summon spells to Ghost/Revive.
Make sure you get the revive mastery too.
This can only be done in Blind Pick as well, unless you luck into being 1st pick and enemy team counts on you banning rammus.
Rammus only has a 60% win rate overall in Dominion. And that is just a little bit higher than Karthus.
rammus does well in blind because people dont like to play good counters for things
best counter to rammus is teemo, by far
