Firebending will always include a number
Once Jumbo Cactuars 10,000 Needles ability triggers and resolves, you can pay the three mana to sacrifice the Cactuar to Jarad to make each opponent lose 10,000 life
Pacifism itself is bad because it is fairly easy to remove and does nothing to stop abilities and static effects
If youd prefer a more surgical approach, Austere Command gives you a lot of scope and flexibility
While it may be expensive at 3WWWW, decks that can afford the restrictive mana cost are rewarded with whats likely to be a game-ending battlefield full of artifacts and enchantments, especially in formats like Commander where games tend to go longer
I had always loved the card Titania's Song from Antiquities , which turned noncreature artifacts into creatures
