The Brothers' War

Tocasia's Welcome | Enchantment | | Whenever one or more creatures with mana value 3 or less enter the battlefield under your control, draw a card. This ability triggers only once each turn. | Johan Grenier

Painful Quandary | Enchantment | | Whenever an opponent casts a spell, that player loses 5 life unless they discard a card. | David Palumbo

Mechanized Warfare | Enchantment | | If a red or artifact source you control would deal damage to an opponent or a permanent an opponent controls, it deals that much damage plus 1 instead. | Robin Olausson

Visions of Phyrexia | Enchantment | | At the beginning of your upkeep, exile the top card of your library. You may play that card this turn. At the beginning of your end step, if you didn't play a card from exile this turn, create a tapped Powerstone token. (It's an artifact with "{T}: Add {C}. This mana can't be spent to cast a nonartifact spell.") | Dominik Mayer
