The timing clause is where this design earns its keep. Ritual mana normally evaporates the instant a step or phase ends, so an attack trigger that dumps green into your pool would be worthless without permission to hold it. This one grants exactly that: the mana persists as steps and phases pass, so the green you generate attacking in combat is still there for the second main phase. The oracle text stops at "until end of turn," so this is a window inside a turn, not a stockpile across turns: use it or lose it as the turn ends. What it produces scales with the attacker's power at the moment it swings, not with damage that connects, so bolting the Equipment onto something large turns a declaration of attackers into a mana surge worth casting into. Left as a creature, it is a modest green body that adds two green when it attacks alone. Reconfigure is the pivot: it can suit up a bigger attacker for a bigger burst, then detach and stand back as a blocker when the board turns. The card asks you to think of combat not as the end of a turn but as a mana step, converting attack power into castable green during a window most ramp cannot reach. It rewards the same instinct that fuels big-mana green: get a fat creature swinging, then have somewhere to put the flood.
