How Does Collect Evidence Work?

Collect evidence is a new type of cost, that some cards can ask you to pay. There isn’t one specific benefit for paying. They vary from card to card.

Collect evidence always has a number associated with it. In order to collect evidence X, you need to exile any number of cards from your graveyard with total mana value X or more.

That’s pretty straightforward, right? In the following section, you’ll find some examples, to see this mechanic in action.


Here’s Analyze the Pollen, an exciting rare with collect evidence 8.

Analyze the Pollen MTG Collect Evidence Rules

With this card, collecting evidence comes as an additional cost when you cast it. You can choose not to pay this cost. In that scenario, you search your library for a basic land card and put it in your hand.

However, you can collect evidence 8. You do so by exiling cards from your graveyard with total mana value 8 or more. (For example, you could exile Ancient Carp and Ancient Carp, as 5+3=8) If you do that, the cards gets a nice upgrade. Now you can search for any land, or for a creature. That’s quite powerful!

More Examples

It’s not necessary for collect evidence to be used as a additional casting cost. It can be used in various ways, as these two examples illustrate.

Izoni, Center of the Web

Izoni triggers both when it comes into play and when it attacks. In both cases, you may collect evidence 4. So, if you exile any number of cards from your graveyard, with total mana cost 4 or more, you’ll get two Spiders for your troubles.

Axebane Ferox

Axebane Ferox is quite interesting, as it combines collect evidence with ward mechanic. If you’re opponent wants to target, they need to collect evidence 4. If they don’t (or can’t), their spell or ability will be countered.

So, if your opponent doesn’t have cards with total mana value 4 or more in their graveyard, Ferox is going to represent a big problem.
