“Though they may talk of things like spirituality, the Leonin of Natia Valley are no more than savages crudely wearing the veneer of civilization.” —Gavis, Stalwart
This spell can't be countered. Creatures you control have ward {2}. (Whenever one becomes the target of a spell or ability an opponent controls, counter it unless that player pays {2}.) When Natural Philosopher enters, you gain 2 life for each creature you control with power 4 or greater.
Defender (This creature can't attack.) When Naturebound Druid enters, you may search your library for a basic land card, reveal it, then shuffle and put that card on top.
Choose two — • Put three +1/+1 counters on target creature. • Target player searches their library for up to two basic land cards, reveals those cards, puts one onto the battlefield tapped and the other into their hand, then shuffles. • Target creature you control fights target creature you don't control. • Target player gains 5 life.
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.
Mill three cards. Create a 1/1 black Skeleton creature token for each creature card milled this way. You draw a card and you lose 1 life for each noncreature card milled this way.
Enchant creature Enchanted creature gets +1/+1. When enchanted creature dies, you may exile it. If you do, return target creature card from your graveyard to the battlefield.
