its my belief due to the popularity of tarmogoyf you can divide magic players into two camp, the with goyfs and without goyfs.
i have experienced bothsides of the fence.
non-goyfs look for intuitive ways to deal with it as almost every tournament you go to you will find a deck running a tarmogoyf. personally i think these are the craftier players.
Pro-goyfs just use goyf for what it is a low cost heavy hitter who can hit people without a goyf on the field or stall a game for a while by having two goyfs face off against each other in a possible never ending combat. reduces the need for innovative stadegy somewhat when you deck needs tactically strong creatures which is why tarmogoyf is so good. personally when i play goyf in a deck a chuck in sword of fire and ice or jitte to give my goyf the upper hand.
but this thread is more tuned to anti goyf.
no i'm not here to talk about lets ban goyf, i find that unproductive. the only way were gunna get rid of goyf is to out play him. maybe wizards will print a new super amazing creature some time in the future but until then.
the most common anti goyf artilery i have noticed employed is the following. my knowledge might be lacking a few things and thats why i have made this thread.
spells like- (but not limited to)
spellsnare- counter 2 converted mana cost spells
mind harnass- to steal green and red creatures for 1

threads of disloyalty- strong kung fu card for turning 0-2 cost creatures against there masters.
veldaken shakels- not the most practical but does sometimes get the job done.
sower of temptation- cost heavy but i see it main bored a lot, i don't think its particularly part of anti goyf ism but it does work.
relic of progenatis- this one just had anti goyf written all over it at first glance.
this thread isn't just for listing side board cards to get rid of the pest, its also about out playing it. i can't help but think in most cases out playing it is going to result in just side board adjustments. the only other is to put anti creature directly into the board least those are the two that come to mind.
i make this thread so anyone else who wants to share anti goyf stradegy or over looked cards for the goyf metagame.
as stated before, i don't see any end to goyf in the future and i believe the only way to oust it is to out play it.
