About the Deckbuild[]
Doublestrike is a 
(Boros) aggro deck.
This deck is built around creatures with Double Strike. The basic idea is to pump those creatures with spells like Invigorated Rampage to bring in massive amounts of damage in the quickest way possible.
There is also a possible turn-4-kill, if you draw 100% perfectly:
- turn 3: play a 2/2 doublestriker
- turn 4: play Kari Zev's Expertise to take control of your opponent's creature (min power 2 or more),
play Invigorated Rampage for free on your doublestriker (now 6/2),
play Titan's Strength on your doublestriker (now 9/2),
attack with both creatures and the opponent is dead
