As long as Adanto Vanguard is attacking, it gets +2/+0.

Pay 4 life: Adanto Vanguard gains indestructible until end of turn. (Damage and effects that say "destroy" don't destroy it.)

Haste

At the beginning of your upkeep, you may sacrifice a creature. When you do, Fireblade Artist deals 2 damage to target opponent or planeswalker.

When Goblin Instigator enters the battlefield, create a 1/1 red Goblin creature token.

Gutterbones enters the battlefield tapped.

{1}{B}: Return Gutterbones from your graveyard to your hand. Activate only during your turn and only if an opponent lost life this turn.

Create two 1/1 white Soldier creature tokens. Until end of turn, creatures you control get +1/+1 and gain haste. (They can attack and {T} this turn.)

When Hunted Witness dies, create a 1/1 white Soldier creature token with lifelink.

Other creatures you control get +1/+0.

Whenever a nontoken creature you control dies, Judith, the Scourge Diva deals 1 damage to any target.

Mentor (Whenever this creature attacks, put a +1/+1 counter on target attacking creature with lesser power.)

At the beginning of combat on your turn, create a 1/1 red Goblin creature token. That token gains haste until end of turn and attacks this combat if able.

Whenever a nontoken creature you control dies, Midnight Reaper deals 1 damage to you and you draw a card.

Spectacle {2}{B}{R} (You may cast this spell for its spectacle cost rather than its mana cost if an opponent lost life this turn.)

When Rix Maadi Reveler enters the battlefield, discard a card, then draw a card. If Rix Maadi Reveler's spectacle cost was paid, instead discard your hand, then draw three cards.

Ascend (If you control ten or more permanents, you get the city's blessing for the rest of the game.)

Skymarcher Aspirant has flying as long as you have the city's blessing.
