Each booster contains 12 Magic cards, 1 art card, and 1 token/promo card as well as any Helper cards or cards from "The List," which includes special cards from Magic's history
But assuming that we dont need to do that in Deaths Shadow, if we move from 60 cards to 70 cards while trying to keep our ratio of lands as similar as possible, we want to add three more lands, and all of them can be additional fetchlands, so now, instead of twelve of our eighteen lands being fetchlands, fifteen of our 21 lands are, so now well draw fetchlands instead of other lands almost 5% more often
Is there some counterbalance that makes C/Viruses stronger on some other aspect
The Locust God: a little on the heavy side, still very Mythic
This makes us confident that the Tropical Mega Battle Trainer Number 1 card would command a similar price point in such condition
