[fixed]Swords of X and Y break rules engine

[gnomefry]

Describe the Bug:

This seems like a whopper of a bug with multiple effects. Please bear with me. I'll attempt to report it as clearly as I can.

There's a set of artifact equipment, the Swords of (X) and (Y), that each give the equipped creature protection from 2 colors and a pair of combat effects.

Sword of Truth and Justice
Sword of War and Peace
Sword of Sinew and Steel
Sword of Light and Shadow
Sword of Fire and Ice
Sword of Feast and Famine
Sword of Body and Mind

These swords seem to break the rules engine or part of the in-game physics governing play and permanents. While I can see and describe various ill effects, it's difficult for me to boil it down to one thing that might be breaking behind the scenes.

Permanents such as planeswalkers or enchantments can be cast, but usually fall off the board and go to grave. But not always. And as I'll report in replies, lands or creatures can also be affected -- albeit less often.

I think the best thing I can do here is post a series of replies, each with a separate example and an attached savegame to demonstrate.

Describe the Bug:

You have in play the planeswalker, Freyalise, Llanowar's Fury and the enchantment creature Nylea, God of the Hunt. Opponent casts Sword of Sinew and Steel. Both Freyalise and Nylea are sent to your grave but then immediately re-appear in the field of play. Despite having only one copy of each in the deck, copies are now both in play and in grave.

Describe the Bug:

Player's turn begins with several equipment Swords in hand: Sword of War and Peace, Sword of Light and Shadow, Sword of Body and Mind, Sword of Truth and Justice, Sword of the Animist and Sword of Kaldra.

Upon casting any of the first four Swords, enchantments that are already already in play (both your Training Grounds and opponent's Oblivion Ring) fall into graveyard. Subsequent enchantments can be cast, but immediately fall off the board.

The final two swords listed above, not part of the color-protection set, can be cast normally and don't affect the enchantments in play.

Describe the Bug:

Casting Sword of Fire and Ice causes your Nahiri, the Lithomancer planeswalker to go to grave.

(In the attached savegame you have Steelshaper's Gift in hand -- use it to fetch the sword and reproduce bug. You can alternately retrieve Sword of Feast and Famine from the deck (same result).

Describe the Bug:

Sword of Light and Shadow is in play. Ajani, Mentor of Heroes is in play at the same time. Unusual for this bug!

But a land, Oran-Rief, the Vastwood, also in play, cannot give freshly cast green creatures the +1/+1 counters. It activates with no result.

Describe the Bug:

I can't say if this equipment issue is directly related. In this scenario 3 non-swords of X and Y equipment are in play: Cranial Plating, Konda's Banner and Loxodon Warhammer. Attempting to cast the creature Puresteel Paladin results in no creature in play and the card goes missing from your hand and graveyard.

Another creature spell in hand, the artifact creature Brass Squire, can be cast without issue.

Describe the Bug:

With two swords in play, Notorious Throng cannot be cast for its Prowl cost, even after dealing combat damage with a rogue.

I've observed Notorious Throng and its Prowl casting to work correctly in other (non-sword) games.

I checked the first few bugs you reported; they are fixed in dev. IIRC, these are duplicates of this: https://www.slightlymagic.net/forum/viewtopic.php?f=86&t=19086&p=220505&hilit=suspend#p201265
