I've always had a deck that was famous for being able to drop a Craw Wyrm (4GG) 6/4 in turn 3. Later, the Yavimaya Wyrm (4GG) 6/4 Trample meant I had to replace that iconic card. Much more recently, I bought my son a box with cards, and his deck has an Aggressive Mammoth (3GGG) 6/6 Trample but gives all your other creatures trample too!

Modern creatures are just so much better than anything we had back then. But my red/blue direct damage deck is suddenly unfair with its lightning bolts and cheap counterspells.
