Feel free to feel your first strike Atog all your Treasures (like it wasn't going to find it anyways), as you two watch White and Black show off how much they hate each other with these two sideboard cards.
Ray of Enfeeblement kills things now?........Why? It only reduces strength, it should absolutely be a blue spell when it comes to Magic reducing attack. Shocking Grasp should have been Ray of Enfeeblement and this should have been literally any warlock/necromantic D&D spell that does damage. What does it have to do against white creatures? What is this? I know this isn't a huge deal, but RoE is such a simple to adapt spell for Magic. I don't get it. Maybe it's me as RoE is a pet spell of mine that has proven to be incredibly useful that many ignore and seeing it represented badly ticks me off a bit.
I get making Rust Monster an Atog/Ravenous Intruder, to some degree, it really should have had a damage trigger to destroy an artifact or even having protection from artifacts. The First Strike is clever in if you consider any metal weapon likely being destroyed swinging at it. This feels a little clunky in representing a Rust Monster, but it's not as bad as Ray of Enfeeblement.
Yeah, I was expecting the rust monster to destroy any equipment attached to a creature it damages, maybe even leaving behind a treasure as the residue. Oh well, a bit of a flavor miss, but it's going to be annoying in treasure-heavy decks.
