When Loresprout enters, if you control another creature, draw a card.

Renown 1 (When this creature deals combat damage to a player, if it isn't renowned, put a +1/+1 counter on it and it becomes renowned.)
When Escort Recruiter becomes renowned, look at the top three cards of your library. You may reveal a creature card from among them and put it into your hand. Put the rest on the bottom of your library in any order.

At the beginning of your end step, Substack Sniper deals 1 damage to you and to each cursed opponent.

Exile the top card of your library. You may play that card until the end of your next turn.

Opera House enters tapped.
When Opera House enters, add one mana of any color.
{T}, Sacrifice Opera House: Search your library for a basic land card, put it onto the battlefield tapped, then shuffle.

Choose one —
• Target creature you control deals damage equal to its power to another target creature or planeswalker.
• Target planeswalker you control deals damage equal to the number of loyalty counters on it to target creature or planeswalker.

Gestalt (When this or another creature enters under your control, you may merge it with the one in play, keeping counters and attachments. They become the permanent on top plus all abilities from under it.)
This creature gets +2/+2 as long as it's merged with another card or token.

As long as your deck contains only green and colorless cards, your minimum deck size is reduced by eight.

Enchant creature
Enchanted creature has “{T}: Add one mana of any color. Put a +1/+1 counter on this creature.”

Greater Sangromancy deals 4 damage to any target. If a permanent dealt damage this way would die this turn, exile it instead. Create a 1/1 black and red Vampire creature token with menace.

Unreflected Cultist can't be blocked by Reflections.

Whenever one or more creatures you control deal combat damage to an opponent, choose up to that many —

• Each player draws a card.

Flamewhip deals 2 damage to each non-Goblin creature.
If you control a Goblin creature, create a 1/1 red Goblin creature token.

When Anran's Radical enters, you may look at the top six cards of your library, then you may discard a card. If you do, reveal a card from among them with mana value 5 or greater or with {X} in its mana cost and put it into your hand. Put the rest on the bottom in a random order.
{T}: Add {C}.

• You gain 5 life.

Whenever Soli Arbalist or a nontoken Angel or Nephilim you control enters, amass Soldiers 2. If it was an Angel, amass Soldiers 4 instead. (To amass Soldiers {2}, put two +1/+1 counters on an Army you control. It's also a Soldier. If you don't control one, create a 0/0 black Soldier Army creature token first.)
