Truthspeaker is the only protect card in my collection, if I'm not mistaking.
Sometimes I slip it in if I have the mana left, but most of the time there is no room for this card. Made a post on the life splinter a few days ago, where I explain my favorite lineup.
Armor is pretty good in earthquake matches, if you don't have good flying monsters, though.
Agree with this... and also, if you don't have flying monsters, playing with cards that have shield is also a good move... Instead of 2 life, earthquake takes only 1 from monsters with shield... ;)
