Outside of decks where its abusive, you are still drawing a pair of cards each time the equipped creature dies
Just about every MTG set has a red sorcery that does one damage to each creature an opponent (or every opponent) controls - with an equipped Ghyrson on the board, that becomes a one-sided board sweeper (indestructible creatures, and creatures with protection from red or blue not withstanding)
Thats not to say you cant make a Boros self-mill deck I see you, Osgir players but the card pool in Sultai will probably rebuild better and outpace other colors trying to self-mill
Shardless Outlander This seven-drop colorless 6/5 trampler is next
You can be much more sinister though, combining Flying Men variants with extra turn spells to hoard all the extra draws for yourself
Aristocrats, Voltron, or counters, all are fair game for this card
