Contempt was a staple for the longest time, not least because it was a great answer to Hazoret the Fervent, but Contempt has been sliding because its heavily played in Standard yet nonexistent in other formats
But its still going to be really strong late in the game
It has 3/4 power and toughness, deathtouch, and a Ward cost of "Get five poison counters." Its final line of text is a triggered ability that reads: "Whenever another creature you control with deathtouch dies, each opponent sacrifices a nontoken creature of their choice." Poison counters, which debuted in 1994s Legends set, are a mechanic that accumulates on a player rather than anything on the battlefield
This Dragon's monstrosity effect is costly, but in return, Stormbreath Dragon becomes a sizeable 7/7, and it deals damage to all opponents to keep the pressure up
The curve is dangerously good with Llanowar Elves on turn 1, and Forest + Mossborn Hydra on turn 2
