First, just to pick a memorable one, heres the Pro Tour debut of one of the most dominant decks of all-time, Caw-Blade: Creatures (8) Planeswalkers (7) Lands (26) Spells (19) 3 Mana Leak 4 Day of Judgment 4 Spell Pierce 1 Deprive 4 Preordain 1 Stoic Rebuttal 1 Sylvok Lifestaff 1 Sword of Feast and Famine Sideboard While this strategy would eventually bring about the only Standard bannings of basically an entire decade, it wasnt the only deck to perform well at PT Paris
It gives your opponents using the same lands the same benefit, but using Snow-Covered Plains usually makes it one-sided in your favor
The Kaldheim God hasn't really developed into a staple in any format, but it has become a popular upgrade for Gylwain, Casting Director Commander decks which are all about loading up creatures with role auras
Life gain is surprisingly useful and can feel like time walking against the right decks
( can be paid with either or 2 life.) Other artifact creatures you control get +1/+1
Is it the design teams at WotC working to live up to the staggering heights of the original Innistrad format
