Experience (Whenever this creature attacks, if it has fewer than three +1/+1 counters on it, put a +1/+1 counter on it.)

At the beginning of each upkeep, choose another permanent with the greatest mana value among permanents. Its controller sacrifices it.

When Roseblood Hart enters, choose one —
• Destroy target artifact.
• Create a Treasure token.

Instant, sorcery, and enchantment spells you cast cost {1} less to cast.

Rosesworn Knight gets +1/+1 as long as it's embattled. (A creature is embattled if it has a counter on it or a permanent you control attached to it.)

When Roving Chaplains enters, create two 1/1 white Spirit creature tokens with flying.
{W}, Tap another untapped creature you control: Tap target nonland permanent an opponent controls.

Whenever Roving Dreadnought attacks, you may salvage a card that was put into your graveyard this turn. (Exile one from your graveyard until this creature leaves the battlefield. Whenever this creature deals combat damage to a player, put a card it salvaged into your hand.)

Ward {2}
Foresight — Whenever you draw your second card each turn, Royal Falconer gains flying until end of turn.

Royster Hounds can't be blocked by creatures with power 2 or less.

[+1]: Up to one other target permanent gains hexproof until your next turn. Untap it.
[–3]: Put target nonland permanent into its owner's library third from the top.
[–8]: Shuffle any number of cards you own from your graveyard and/or outside the game into your library. You get an emblem with “Permanents you control have ‘{T}: Draw a card.'”

Create a 0/0 green Wurm creature token with “This creature gets +1/+1 for each permanent card in your graveyard.”
If you would draw a card, you may instead sacrifice two lands and mill two cards. If you do, return Ruchong Awakening from your graveyard to your hand.

Flying
If a +1/+1 counter would be put on a creature you control, you may instead put your choice of a flying counter, a vigilance counter, or a trample counter on it.

As long as you control another artifact, Ruin Guardian gets +1/+1.

Haste
Ruin Shark attacks each turn if able.
Ruin Shark gets +1/+0 and has first strike as long as you've drawn two or more cards this turn.

Whenever you cast a cryptic spell, creatures you control get +1/+1 until end of turn. (Artifacts, enchantments, and modal spells are cryptic.)

Trample
Whenever a noncreature permanent is put into a graveyard from the battlefield, put a +1/+1 counter on Ruinous Naga.

{1}, Sacrifice Ruinous Proselyte: Destroy target artifact or nonbasic land.

Ruins Pack gets +2/+2 as long as you sacrificed a permanent this turn.

When Ruins' Reward enters, draw a card, then discard a card.
{T}: Add one mana of any color.

Target opponent sacrifices a creature. Create an X/X black Zombie creature token, where X is the sacrificed creature's power.

At the beginning of your end step, Run & Gun deals damage to each opponent equal to the number of tapped creatures you control.

At the beginning of your upkeep, you may put a card from your graveyard on the bottom of your library. If you do, you gain 2 life.
{2}, Sacrifice Rune of Rejuvenation: Draw a card.

Return target instant or sorcery card from your graveyard to the battlefield face down. It gains metamorph. The metamorph cost is equal to its mana cost. (It's a 2/2 creature. Turn it face up and cast it at any time for its metamorph cost.)
