Krosan Tusker was the best because it gave Green a powerful tool it rarely had before - card drawing
Your pet cards that were too expensive in previous sets like the wonderful Fairy Godmother, Mystic Armorer or Snow White, Well Wisher will now be a lot easier to shift out if theyre paired with Emerald and this globby little guy
Do your best to clear the way for Squee because you dont want to rely on casting this dubious noble from the graveyard
This is the sweet spot where a single search land can pull a triome that taps for all three of your colors, effectively turning one card into a perfect mana source
Lands specifically being so simple is a big reduction in mental load, and while there are technically differences between the back (Plain ETB tapped vs ETB tapped unless you pay 3 life), it's not enough that I would (for eg) only run one of those kinds if the front faces both felt right
When you attack, both players decide what side of the battlefield their creatures go to, and any creatures on one side of the battlefield cannot block or be blocked by creatures on the other (represented by the fact that they're on opposite sides of the river)
