MTG Boros Midrange Deck by Sodeq

Flying Other Dragons you control get +1/+1. Storm (When you cast this spell, copy it for each spell cast before it this turn. Copies become tokens.)

Red spells you cast cost {1} less to cast.

{3}, {T}: Reveal cards from the top of your library until you reveal a land card. This artifact deals damage equal to the number of nonland cards revealed this way to any target. If the revealed land card was a Mountain, this artifact deals double that damage instead. Put the revealed cards on the bottom of your library in any order.

When this enchantment enters, you may discard a card. If you do, draw two cards. {1}, Sacrifice this enchantment: Creatures you control gain haste until end of turn.

Nonbasic lands are Mountains.

Add {R}{R}{R}. Splice onto Arcane {1}{R} (As you cast an Arcane spell, you may reveal this card from your hand and pay its splice cost. If you do, add this card's effects to that spell.)

Add {R}{R}{R}.

Add two mana in any combination of colors. Draw a card.

Create a Treasure token. (It's an artifact with "{T}, Sacrifice this token: Add one mana of any color.") Flashback {2}{R} (You may cast this card from your graveyard for its flashback cost. Then exile it.)

Add seven {R}. You can cast only one more spell this turn.
