Custodi Soulbinders 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
This creature enters with X +1/+1 counters on it, where X is the number of other creatures on the battlefield., Remove a +1/+1 counter from this creature: Create a 1/1 white Spirit creature token with flying.
Complete guide
Custodi Soulbinders is a dynamic Human Cleric that thrives in crowded environments, growing stronger as the battlefield fills with life. It serves both as a massive threat and a persistent engine for generating evasive tokens. By harnessing the presence of others, it ensures you always have a way to expand your board state.
Scaling Power
Custodi Soulbinders has a replacement effect that modifies how it enters the battlefield. It checks the total number of other creatures currently in play, including those controlled by your opponents. Based on this count, it arrives with that many +1/+1 counters, making it significantly more powerful in multiplayer games or against swarm decks.
Token Generation
Once on the battlefield, you can pay two mana and a white mana while removing a +1/+1 counter from it to create a 1/1 white Spirit token with flying. This activated ability can be used at any time you have priority, including during an opponent's turn. It allows you to convert the creature's raw power into multiple flying blockers or attackers.
Timing and Limits
Because the first ability is a replacement effect rather than a triggered ability, it does not use the stack and cannot be responded to once the spell begins to resolve. However, the activated ability requires the removal of a counter as a cost. If Custodi Soulbinders has no +1/+1 counters left, you cannot activate the ability to create more Spirits.
When to Play It
This card is most effective when the board is 'wide.' Ideally, you want to cast this when there are at least three or four other creatures present to ensure it stays out of range of toughness-based removal. It is a fantastic mana sink for late-game scenarios where you need to create a flying army to bypass ground-based defenses.
Interaction examples
If you control a Solemn Simulacrum and your opponent controls two other creatures, Custodi Soulbinders will enter the battlefield with three +1/+1 counters. Even though it is a 0/0 base creature, it survives because the counters are placed on it as it enters, not after it is already on the battlefield.
With Custodi Soulbinders on the field with four +1/+1 counters, you can pay three mana and remove one counter. This places a 1/1 Spirit token with flying onto the battlefield. Custodi Soulbinders becomes a 3/3, and you now have a new creature that can be used to block or trigger other enter-the-battlefield effects.
If you name 'Human' or 'Cleric' with Roaming Throne, it will not affect how many counters Custodi Soulbinders enters with, because that is a replacement effect, not a triggered ability. Additionally, Roaming Throne does not double the Spirit production because that is an activated ability, not a triggered one.
