There are two inherent triggered abilities associated with being the monarch
Martial Impetus costs three, gives the dork a +/+1 in size and then when it swings the other attackers (attacking your foe) get a +1/+1 boost in size
Because this a Standard set that's built to draft, there does feel like there is overlap in what some of the legends do, but that just means you can personalize your approach
More than just being a Dinosaur card, though, its perfectly usable as a Group Slug piece or as an accelerator for aggressive decks
Midrange decks should like this most of all and even more so in aggro and midrange matchups
These cards offer unique abilities and effects, such as ward, wither, and the ability to copy triggered abilities, making them powerful additions to any Magic: The Gathering deck
