Rite of the Raging Storm creates tokens that sacrifice themselves at the end of your opponents turn, and, while they dont necessarily have to attack each turn, but theres little reason not to send it in at another player.Even if they dont attack, the token will still trigger effects that happen when a creature dies, like Morbid Opportunist
Trinket Mage gives a bunch of powerful but narrow options like Relic of Progenitus, Engineered Explosives, and Chalice of the Void
However, you can also pay one and a Blue to cycle it, and when you do so, each opponent mills four cards, so its got a little bit of versatility to it, which is nice
This card is so influential that the word tutor became the everyday term for any effect that lets you search for a card
