Neckbreaker Viking gets +1/+0 and has menace as long as it's embattled. (A creature is embattled if it has a counter on it or has a permanent you control attached to it.)
Cultivating a reputation for egregious brutality can clear a viking's path like any weapon.
Creatures your opponents control get -1/-1 until end of turn. You gain 2 life.
“A sunlit haze, a scarlet streak, the decorations torn to shreds. Platoon assassinations are simply gorgeous this time of year.” —Ryleth, Vengeful Shadow
“I don't know what's more insulting— that you thought I wouldn't see that coming, or that you thought it would actually work.” —La of the Highpoint Three
When Neo-Alchemist enters, you may reappropriate. If you do, distribute two +1/+1 counters among creatures you control. Otherwise, put a +1/+1 counter on up to one target creature you control. (To reappropriate, exile exactly two cards from your hand and/or graveyard.)
Deathtouch When Neophyte of the Old Gods enters, rediscover a sorcery card. (Look at the top card of your library. You may reveal it and put it into your hand if it's a sorcery card. Otherwise, put it back or into your graveyard.)
“Sign by sign, power by power, our true gods give me the life I was meant to live.”
Colossal 2—{4}{G}(You may cast this for its colossal cost to have it enter with two +1/+1 counters; or pay {4}{G} as a sorcery: Put two +1/+1 counters on it if it has none.) Reach
“What a beaut of a spider, this one is!” —Vivien Reid
Whenever Netsight Trickster deals combat damage to an opponent, create a Function token with “Draw a card. Then discard a card unless you pay {2}.” (It's an enchantment. As you cast an instant or sorcery spell, sacrifice any number of Functions to add their effects to that spell.)
Choose one — • Exile target permanent you control, then return that card to the battlefield under its owner's control. • Return target permanent you control to its owner's hand. Draw a card.
