how to price mtg cards I'm a tad new the game. Can someone explain costing exactly works? The cost on the left is obvious. It wants 2 Blue Mana. But the one on the right? Price of Progress deals damage to each player equal to twice the number of nonbasic lands that player controls. Presented for your nostalgia -

Plus, they have a lot of high-ceiling cards in Biolume Egg, Soulcipher Board, Whispering Wizard and Stormchaser Drake any of which will randomly win games in their respective archetypes

She also only triggers when you sacrifice creatures rather than whenever they might die which greatly ups the burden on sac outlets

Milling your opponent is actually positive for them unless you can finish them off, and there simply isnt enough lifegain to enable Hope as a potential win condition

Both of these cards are going off in Pioneer and work with the same basic combo strategy, stuffing your deck full of high mana cost cards that either have cost reductions (Leyline Binding) or can be exploited in other ways (ramping off Beanstalk Giant)
