Each Rogue you control can't be blocked by creatures with greater power than it.
Whenever a Rogue deals combat damage to a player, gain control of target nonland permanent that player controls unless that player pays {1}.

Look at the top four cards of your library. Put two of them into your hand and the rest on the bottom of your library in a random order. Create a tapped Treasure token.

Reveal the top three cards of your library. You may put a land card from among them onto the battlefield tapped, then you may put a creature card from among them into your hand. Put the rest on the bottom of your library in any order.

Choose one or both —
• Target player searches their library for a basic Plains card, reveals it, put it into their hand, then shuffles.
• Exile target permanent you control, then return it to the battlefield under its owner's control.

Prowess
At the beginning of combat on your turn, if a permanent you controlled left the battlefield this turn, target creature can't block this turn.

At the beginning of your upkeep, put a +1/+1 counter on Heyu, Immortal Hunter.
Whenever Heyu becomes the target of a spell or ability an opponent controls, counter it if Heyu has the greatest power among creatures on the battlefield.

Flying
When Highspire Informant enters, scry 1.

Trample
At the beginning of combat on your turn, create a 1/1 red Lizard Warrior creature token with haste and winnow. (Damage dealt to that token also causes you to lose that much life.)
Whenever Fang of Anaz attacks, it gets +1/+0 for each other attacking Lizard you control until end of turn.

You don't lose the game for having 0 or less life.
Whenever you're dealt damage, mill that many cards.
{B}, Pay 2 life: Put target card in your graveyard on the bottom of your library.

Whenever a nontoken permanent you control leaves the battlefield, create a token that's a copy of it. Exile the token at the beginning of the next end step.

Indestructible
Spells you cast from your graveyard cost {6} less to cast.
Whenever you attack, you may cast any number of target cards from your graveyard this turn. If a spell or permanent that was cast this way would be put into a graveyard, exile it instead.

Whenever a player looks at one or more cards in your library or searches your library, Lavamind Elemental deals 2 damage to that player. (This includes you.)
At the beginning of your end step, look at the bottom card of your library. You may put it on top of your library.

At the beginning of your end step, untap all lands you control. You may put three +1/+1 counters on target land you control. If you do, that land becomes a 0/0 Treefolk creature with haste that's still a land.

{T}: Add {C}.
{1}, {T}: Add {B}{G}.

Menace
As long as you control exactly one other creature, that creature gets +1/+1 and has menace.

Ward—Pay 3 life.
Igniderm enters with three ignition counters on it.
At the beginning of your upkeep, remove an ignition counter from Igniderm. If you can't, sacrifice it.

Target creature gets +2/+1 and gains haste until end of turn.
Agonize (You may cast this card from your graveyard by putting a -1/-1 counter on a creature you control in addition to paying its other costs. Then exile this card.)

At the beginning of each end step, if you've cast a noncreature spell this turn, amass Soldiers 1. (Put a +1/+1 counter on an Army you control. It's also a Soldier. If you don't control one, create an 0/0 black Soldier Army creature token first.)

{G}, Discard a noncreature card: Reveal the top five cards of your library. You may put a creature card with mana value X or less from among them into your hand, where X is the discarded card's mana value plus one. Put the rest on the bottom of your library in any order.

Target creature gets -4/-4 until end of turn.

Each player discards two cards. Then if there are four or more card types among cards in your graveyard, create two 1/1 white Human creature tokens.

Trample, haste
Respawn (When this creature dies, if it attacked this turn, return it to its owner's hand.)
At the beginning of your end step, sacrifice a creature.

When 1-ST Thankless Companion enters, draw a card.

Flash
Enchant creature
Enchanted creature gets +1/+1 and has “Whenever this creature deals combat damage to an opponent, draw a card.”

{1}{G}: Marrow Gorger must be blocked this turn if able.
