In my observation of the past Magic: the Gathering Standard rotations, one of the archetypes that are easily adopted in the metagame is the Mono-Red Aggro deck. It might be a given that the R&D of Wizards has been continually making Red cards either creatures or spells that are efficient in supporting their nature of being aggressive and fast and dealing damage as early as possible.

That may be the primary reason why as I was browsing through the Dominaria United card spoilers, I can spot easily the potential Red cards for an updated Mono-Red Aggro deck after the rotation. In that regard, here below is the deck tech video I made for the archetype and uploaded it on my Youtube channel.
