This effectively doubles +1/+1 counters on creatures, which is good, but this equipment can also be attached to planeswalkers, turning them into creatures that can still use their loyalty abilities
The aim is to have lots of creatures that benefit from your casting non-creature spells, and then cast lots of spells, attack and win the game
Bog-Strider Ash was meant to play against the red/black goblin decks of the format and is a tough blocker, a Swampwalker, and can grant you life when your opponent plays goblins (notoriously a thing goblin decks do a lot of)
Additionally, this is also a popular combo deck in Explorer at the moment, so spending your wildcards on it will allow you to play the deck across multiple formats
And I love that Marshland Bloodcaster also helps you discount any spell you want by paying life for it instead
