Ihyafhsma's Will

From Telkoth.net

Telkoth: ! there's an awesome green enchantment which would make your artifact deck cry:
Telkoth: it fucks over non-basic land somehow
Telkoth: it either deals damage to the controller during their upkeep, or maybe it turns them all into forests
[Katie]: hm
Telkoth: heh
[Katie]: you told me about some other card that deck would hate
[Katie]: I don't remember what it was
Telkoth: yeah
Telkoth: there are lots of cards that are good at hating specific deck types
Telkoth: most are colored
Telkoth: i.e. not available to artifacts
Telkoth: heh - I saw on-line an artifact which makes artifact spells cost their caster one more mana for each artifact the caster controls :P
[Katie]: yeah, that's the one
Telkoth: anti-affinity
Telkoth: heh
Telkoth: well, there are also classics like red's Shatter Storm - destroy all artifacts - and white has an enchantment which makes artifacts and enchaments cost 2 more
Telkoth: and I'm making up a card right now, a sorcery which reads "if the total number of artifacts controlled by opponents divided by the number of opponents (round down) is greater than your life total, you win the game."
Telkoth: it's, um, called "I hate you all for having so many artifacts"
Telkoth: or "Ihyafhsma's Will"
[Katie]: hmmm
