Not sure if anyone posted this yet or not, but {Guardian of the Gateless} can block all of your opponents creatures, and the {Ghostly Posession} prevents it from taking any combat damage. This basically leaves all your other creatures open to attack. I think overflow trample damage would carry through, but a good amount can be prevented.
Maybe try {Holy Mantle} instead? That way it can kills what it blocks (in some cases anyway)
I also like to try and give it lifelink as well. :)
Not bad at all, and if you give it vigilance, you have an unstoppable attacker as well, I like it, thanks a lot
Throw a good ol {venom} + mantle + hexproof equip or enchant and you've got a damn good wall
Venom fits perfectly in there actually
If you just wanted a blocker, {Goldenglow Moth} works well
Guardian can block any number of creatures though.
Aww, dang, for a minute I thought {glow moth} could also :(
