I haven't played Magic the Gathering since Saviors of Kamigawa.
In a few words, (or perhaps card spoilers).....what's the biggest "stuff" I've missed?
Anything as OP as Affinity was during Mirrodin block? New card types and mechanics?
Probably not going to start playing again, but I do like learning about what's been happening.
OK...
1.) Planeswalkers were introduced as a card type in 2007, and have fundamentally changed Magic as a whole. It's hard to put into words how different Magic is today because of them
2.)We have had 2 points in standard that have required bannings since Saviors. The first was in 2011, where Stoneforge Mystic and Jace The Mind Sculpter got banned due to a deck called Caw-Blade, which is widely considered by pro players to be the greatest standard deck of all time.
Right now, we are probably in the midst of the worst standard since the Affinity Bans. 3 cards are banned right now- Emrakul the Promised End, Reflector Mage and Smugglers Copter. Unfortunatly, standard has gotten EVEN WORSE since those bannings, as they inexplictly printed a 2 card instant win combo in back to back sets, and their recent ideas of pushing threats while downgrading answers has led to cards like Gideon, Ally of Zendikar constraining the format down to 2 archtypes.
3.) We have new formats/release schedules. Extended no longer exists, and has been replaced by Modern, a format that allows cards from 8th edition to present day, and has no rotation. "Blocks" are 2 sets now, so each year features 4 expansions/2 blocks
