Auras that become Equipment while losing their other types are likely to not grant abilities to "enchanted" creature as expected

As clarified by the rulings on [Bludgeon Brawl](https://github.com/Card-Forge/forge/blob/master/forge-gui/res/cardsfolder/b/bludgeon_brawl.txt) and similar effects and stated by [**CR303.4m**](https://mtg.wiki/page/Enchantment) (both quoted), the "enchanted [quality]" line on Auras refers to the object the attaching permanent is attached to regardless of whether the attaching permanent is an aura or not.

> "While Bludgeon Brawl is on the battlefield, an Aura enchantment that somehow becomes an artifact in addition to its other types will also become an Equipment. Any of its abilities that refer to either “enchanted creature” or “equipped creature” refer to the creature it’s currently attached to. It can be attached to other creatures using its equip ability. If you try to attach the Aura Equipment to a creature it can’t legally be attached to, it remains where it is. If the creature it’s attached to becomes an illegal permanent for it to enchant, the Aura Equipment will be put into its owner’s graveyard as a state-based action."

> "**303.4m** An ability of a permanent that refers to the “enchanted [object or player]” refers to whatever object or player that permanent is attached to, even if the permanent with the ability isn’t an Aura."

This is something chiefly relevant for the rare cases an attaching permanent gains the Equipment subtype while not being an Aura at the same time.
The current generalized line for this are effects that have a permanent with text that affects objects they attach to (Auras, [bestow creatures](https://scryfall.com/search?q=o%3Abestow&unique=cards&as=grid&order=name), [Licids](https://scryfall.com/search?q=t%3Alicid&unique=cards&as=grid&order=name), etc.) become an artifact while losing all other card types but keeping their abilities ([Captain Rex Nebula](https://scryfall.com/card/unf/164/captain-rex-nebula), [Vraska, the Silencer](https://scryfall.com/card/otj/237/vraska-the-silencer), [Reezug, the Bonecobbler](https://scryfall.com/card/ydmu/10/reezug-the-bonecobbler), etc.) which then can be affected by Bludgeon Brawl-type effects.
This seems fiddly to get to work on Forge: I have Rex targeting an [Abundant Growth](https://scryfall.com/card/inr/184/abundant-growth) with its phase trigger. There's both a Bludgeon Brawl and a [Leonin Shikari ](https://scryfall.com/card/c17/66/leonin-shikari)on the battlefield. The Aura gets converted into a Vehicle, gets the "Equipped creature" line, the equip ability but doesn't get the Equipment subtype, so attaching it to anything is a nonstarter. A [Quickening Licid](https://scryfall.com/card/tmp/36/quickening-licid) cast from the graveyard via Reezug's ability results in the same. For both, resolving a subsequent Bludgeon Brawl does have them gain the Equipment subtype and I can equip them normally. Bit of a perplexing outcome; I'm not sure if I'm misunderstanding how this works out in regards to layers. In any case, the relevant gamestate files are appended for testing convenience.

All that said, looking over relevant attaching permanent scripts, it's noteworthy how some use restrictive arguments in their `Affected$` parameter to limit how their continuous effects apply, such as the [Shadowmoor/Eventide demigod Aura cycle](https://tagger.scryfall.com/tags/card/cycle-demigod-aura) (see [Steel of the Godhead](https://github.com/Card-Forge/forge/blob/master/forge-gui/res/cardsfolder/s/steel_of_the_godhead.txt), for instance). There's also the current state of affairs where the most generalized, tested-as-working argument for `Affected$` and other relevant parameters, `Card.AttachedBy`, is fairly underrepresented, at 172 hits in 158 files against (just) 1238 files with Aura in their type line. It's clear then, that even if you play the cards right, a good number of cards relevant to the situation at hand might not work as expected, because of how they're coded to follow the lead of their "Enchant [quality]" ability.
