Shadowverse

Yes, I'm being slow again. Regarding the icons, it seems to follow a similar logic to Blizzard: the ones for poison (similar to Bane) only had a name introduced in this expansion, when the effect became common enough. As for the effect "You and your opponent reveal a card from your deck. If your card has a higher cost, it does X," they never came up with a name and just wrote it out on the cards. So, maybe if there are more clashers in the future, they'll create an icon for it.
