Copying cards like Dig Through Time, Beast Within, and Artifact Mutation on every turn is a plan I can get behind, and by the time your turn comes back around, Kalamax will be swinging at opponents for a lot more damage to boot
Increasing the cards milled each turn is an attractive solution, creating a reliable one-card mill engine for any format
However, in the same example, if a 2/2 enters the battlefield, neither its power nor toughness exceeds that of our 2/2 Watchful Radstag, so Evolve will not trigger at all
The Masamune has great synergy with Deathtouch strategy and Shelob, Child of Ungoliant as Deathtouch combined with First Strike and a lure effect becomes an excellent removal tool
For example, if you copy Assault, the copy is also Assault, not Battery
When you attack, you get to make two tokens, so its good on offense too
