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.

As an additional cost to cast this spell, you may exile any number of red cards from your hand. This spell costs {2} less to cast for each card exiled this way. Exile the top X cards of your library. You may play up to two of those cards until the end of your next turn.

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.
