Knight in _____ Armor is one of those cards players keep asking about. Here is, in plain words, what its official text says, the rulings published by Wizards of the Coast, and the combos players actually run.
Official card text
First strike As this creature enters, you may put a name sticker on it. This creature has protection from names that start with the same letter as a name sticker on it.
Complete guide
Step into the spotlight with Knight in _____ Armor, a unique performer that utilizes stickers to shield itself from specific threats. This card allows players to customize their defenses by choosing which letters they are most afraid of on the battlefield. With its flexible protection and first strike keyword, it is a versatile addition to any sticker-themed deck.
Sticking the Name
As Knight in _____ Armor enters the battlefield, you have the choice to place a name sticker on it from your available sticker sheets. This is a replacement effect that happens as the creature enters, so it does not use the stack and cannot be responded to once the creature begins to resolve. The sticker you choose defines its protection ability for as long as that sticker remains on the permanent.
Alphabetical Protection
The creature gains protection from names starting with the same letter as any name sticker currently on it. When checking the first letter of a name, the rules specify that you must ignore all spaces and punctuation. For example, if your sticker starts with 'E', the Knight has protection from any card whose name begins with 'E'. This protection includes all standard benefits: the Knight cannot be damaged, enchanted, equipped, blocked, or targeted by sources meeting that criteria.
Common Mistakes
A common error is thinking that the Knight has protection from the sticker itself; however, the protection applies to other names, not the sticker providing the letter. Additionally, remember that if you choose not to put a name sticker on the Knight as it enters, it will not have any protection at all, though it will still retain its first strike ability.
When to Play It
Knight in _____ Armor is most effective when you can anticipate the opponent's key cards. By selecting a sticker that matches the first letter of their removal spells or their strongest blockers, you can create an untouchable threat. It is also a low-cost creature that can benefit from other sticker-related synergies in the Unfinity set.
Interaction examples
If you place a sticker like 'Eternal' on Knight in _____ Armor, it gains protection from names starting with 'E'. If your opponent controls Esper Sentinel, the Knight can now attack without fear of being blocked by the Sentinel, as creatures with protection cannot be blocked by creatures of the protected quality.
Suppose you apply a sticker starting with 'O', such as 'Oozing'. Knight in _____ Armor now has protection from names starting with 'O'. Even though Ornithopter of Paradise has flying, it cannot block your Knight because of the protection ability, allowing you to strike your opponent directly.
