At the beginning of your upkeep, you may pay 2 life. If you do, exile the top card of target opponent's library. If a nonland card is exiled this way, copy it. You may cast the copy. (You still pay its costs, including color. Copies of permanents enter as tokens.)

Draw a card. Then you may cast an instant spell with mana value 2 or less from your hand without paying its mana cost.

Flying
Prophecy {0} (Once each turn, you may exile a card with prophecy as you reveal it. When you do, you may cast it for its prophecy cost as long as it's exiled.)

Target creature gets -2/-2 until end of turn. If you control two or more Deserts, destroy that creature instead.

Look at the top three cards of your library. Put one of them into your hand and the rest into your graveyard.

Target creature gets +2/+2 until end of turn. Untap it.

Stratospheric Bombardment deals X damage to any target and you gain that much life.

Creatures blocking or blocked by Straw Officer have wither. (They deal damage to creatures in the form of -1/-1 counters.)

Stray Sighthound can't be blocked by creatures with power 2 or less.
Attain {3}{G} ({3}{G}: Transform this. Spend at least three colors of mana to activate this, and only as a sorcery.)

Return target creature to its owner's hand.
Draw a card.

At the beginning of your end step, if you control two or more tapped creatures, exile the top card of your library. Until the end of your next turn, you may play that card.

Wither (This deals damage to creatures in the form of -1/-1 counters.)

When Street Performer enters, create a 2/1 blue Illusion creature token with “When this creature becomes the target of a spell or ability, sacrifice it.”

Menace
Deploy 4 (As this enters, you may tap any number of other creatures you control with total power 4 or more.)
When Street Raider enters deployed, discard your hand, then draw three cards.

Improve {1} ({1}: Put a +1/+1 counter on this creature. This costs {1} more to activate for each +1/+1 counter on it. Improve only as a sorcery.)
At the beginning of combat on your turn, target creature you control with mana value 3 or less can't be blocked this turn. If Streetwise Investigator has two or more counters on it, that creature gains vigilance until end of turn.

At the beginning of each end step, if you've cast a noncreature spell this turn, put a +1/+1 counter on Streetwise Spellseeker. Then if its power is 5 or greater, create a 4/4 white Angel Soldier creature token with flying.

Choose one or both —
• Audition for green. (Create a 1/1 Construct Actor creature token, a Scout Role giving 2/3 and vigilance, or a Warrior Role giving 3/2 and trample. Roles replace older ones.)
• Target creature you control fights target creature you don't control.

When Strength of the Patient enters, if it was revived, put four +1/+1 counters on it.
Revive {4}{W}{W}{W} ({4}{W}{W}{W}, Exile this card from your graveyard: Create a token that's a copy of it except it has no mana cost. Revive only as a sorcery.)

Counter three target spells.

Target creature gets +2/+0 and gains flying and first strike until end of turn.

Destroy target non-Assassin, non-Ninja, non-Rogue creature.

Create a Treasure token.
Showcase {2}{R} (Then if you cast this for its showcase cost, create a 1/1 red Bard creature token that can't block and exile this. Whenever it attacks, you may cast a free copy of this.)

Whenever another Warrior creature you control attacks, you may return Stubborn Blademate from your graveyard to the battlefield tapped and attacking. If you do, sacrifice it at end of combat.

Defender
Prowess (Whenever you cast a noncreature spell, this creature gets +1/+1 until end of turn.)
{T}: Student of Lightning deals damage equal to its power to target player.
