Double strike

Double strike is an evergreen keyword ability that allows a creature to deal combat damage twice per combat phase — once during the first combat damage step, along with any creatures that have first strike, and again during the second combat damage step along with creatures that have neither keyword.
==Description==
Double strike appears primarily in Red and in White, the two combat-trained colors already proficient with first strike. Even among creatures that aren't red nor white, all but four (Planar Chaos card <c>Jodah's Avenger</c>, the multicolor-requiring <c>Scuttling Butler</c>, and red and white aligned <c>Phyrexian Dragon Engine</c> and <c>Combat Thresher</c>) still require in some way to utilize double strike. 
===History===
Double strike was designed by Wayne Alward, a player who submitted it as a mechanic for the first You Make the Card promotion. Double strike was rejected for the card, which would later become <c>Forgotten Ancient</c> because the mechanic didn't fit within Green's segment of the color wheel. Nonetheless, several R&D members were impressed with the design's elegance. Thus, double strike was adopted into Magic, upon which it became evergreen almost immediately. 
Double strike premiered in Legions, with the cards <c>Ridgetop Raptor</c> and <c>Rockshard Elemental</c>. It remains an evergreen mechanic today. However, its power means it has only a small representation each set, and it does not appear at common often. <c>Two-Headed Cerberus</c> was the first common native double striker, a decade after its introduction in Theros.
Ikoria Commander introduced double strike counters.
==Rules==
==Rulings==
*Double strike isn't first strike. Effects that make a creature lose first strike won't make it lose double strike.
*Creatures with double strike and creatures with first strike deal combat damage in the first combat damage step.
*If a creature with double strike is blocked, it remains blocked even if the blocking creature is destroyed in the first combat damage step.
*All creatures that didn't assign combat damage in the first combat damage step assign combat damage in the second combat damage step. In addition, all creatures with double strike assign combat damage again in the second step.
*If a creature has both double strike and trample, the combat damage it assigned during the first combat damage step will be considered when determining how much damage can trample through in the second combat damage step.
