Ice Age , surprise, surprise, was released under the name Ice Age (this was before we started using wacky playtest names to ensure that playtest names didn't just turn into the actual set names)
There are different card rarity levels indicated on each card, with the Enchanted cards being the rarest of the standard, non-promotional sets
Creatures (3) Lands (16) Spells (41) 4 Serum Visions 4 Peer Through Depths 4 Desperate Ritual 4 Seething Song 4 Rite of Flame 4 Empty the Warrens 4 Ponder 4 Manamorphose 4 Preordain 2 Pyretic Ritual 3 Gitaxian Probe Sideboard Sleight of Hand verus Opt is just a sorcery versus instant question
To determine the total cost of a spell, start with the mana cost or alternative cost you're paying (such as a flashback cost), add any cost increases (such as kicker costs), then apply any cost reductions (such as that of Danitha Capashen's last ability)
Its a classic inclusion in any red-white deck and can single-handedly save your entire board from a wrath effect when needed
