MTG Mardu Midrange Deck by Ambivalentcy

Whenever another creature you control enters, you gain 1 life and get {E} (an energy counter). Whenever you attack, you may pay {E}{E}{E}. When you do, put two +1/+1 counters and a flying counter on target attacking creature. It becomes an Angel in addition to its other types.

First strike, lifelink Ascend (If you control ten or more permanents, you get the city's blessing for the rest of the game.) At the beginning of your end step, if you gained life this turn, create a 1/1 white Cat creature token. Then if you have the city's blessing, for each token you control that entered this turn, create a token that's a copy of it.

Flash Whenever Phelia attacks, exile up to one other target nonland permanent. At the beginning of the next end step, return that card to the battlefield under its owner's control. If it entered under your control, put a +1/+1 counter on Phelia.

At the beginning of combat on your turn, exile up to one target card from a graveyard. {1}{B}: Adapt 2. Whenever one or more +1/+1 counters are put on this creature, put a creature card exiled with this creature onto the battlefield under your control with a finality counter on it. It gains haste. Sacrifice it at the beginning of the next end step.

Flash When this creature enters and whenever an opponent draws a card except the first one they draw in each of their draw steps, this creature deals 1 damage to any target. Then amass Orcs 1.

When this creature enters, discard two cards, then draw two cards. For each nonland card discarded this way, create a 1/1 red Elemental creature token. {3}{R}{R}, Exile this card from your graveyard: Create two 1/1 red Elemental creature tokens.

When Phlage enters, sacrifice it unless it escaped. Whenever Phlage enters or attacks, it deals 3 damage to any target and you gain 3 life. Escape—{R}{R}{W}{W}, Exile five other cards from your graveyard. (You may cast this card from your graveyard for its escape cost.)

Impending 5—{1}{B} (If you cast this spell for its impending cost, it enters with five time counters and isn't a creature until the last is removed. At the beginning of your end step, remove a time counter from it.) Whenever this permanent enters or attacks, mill four cards, then you may return a non-Avatar creature card or a planeswalker card from your graveyard to your hand.

Sacrifice a creature: This enchantment deals 1 damage to any target.

(As this Saga enters and after your draw step, add a lore counter. Sacrifice after III.) I — Exile the top four cards of your library. Until the end of your next turn, you may play those cards. II, III — Whenever you cast a spell this turn, put a +1/+1 counter on target creature you control.

Destroy target creature if it has mana value 2 or less. Revolt — Destroy that creature if it has mana value 4 or less instead if a permanent left the battlefield under your control this turn.

Choose one — • Thraben Charm deals damage equal to twice the number of creatures you control to target creature. • Destroy target enchantment. • Exile any number of target players' graveyards.

Target player reveals their hand. You choose a nonland card from it. That player discards that card. You lose 2 life.
