The reason why I went for Exsanguinate over Torment, is, frankly, the budget
Landfall decks would do anything to get more triggers, some cards need you to sacrifice lands, and you can even use them to assemble combos like Dark Depths and Maze's End
The tokens created by Alela are blue, so if you want to play an effect like Heraldic Banner just choose blue for an extra +1/+0
(A copy of a permanent spell becomes a token.) Triggered abilities use the word "when," "whenever," or "at." They're often written as "[Trigger condition], [effect]." Some keyword abilities are triggered abilities and will have "when," "whenever," or "at the beginning of" in their reminder text
The moment an Active Pokemons HP becomes zero, it gets knocked out and therefore, must be sent to the discard pile, and be replaced by a Benched Pokemon
