Planeswalkers either saved Magic or ruined the game, depending on who you talk to, but its clear that theyve been a pivotal card type in the development of Magic since their release in Lorwyn
These towering creatures were predominantly focused in green for many years fittingly, Id say until the Lorwyn-Shadowmoor block introduced white and black kindred support for Magic s leafy giants (though the Golgari-colored Ebony Treefolk from 2001s Apocalypse was the first non-green Treefolk in the games history)
The loss of surprise and free information for opponents often comes with a significant tempo advantage, as Suspend cards could be cast for less mana
Alacrian Armory: Auto-piloting more reliable than a Tesla, thats for sure
At the same time, control and even (maybe!) tempo get some of the better tools theyve had in a while
Case in point, see the Amonkhet plains that was posted above
