Declare blockers step

The declare blockers step is a step of the combat phase, where attacking creatures may be blocked.
Creatures assigned in this step are blocking. 
==Blocking mechanics==
===Blocking extra creatures===
By default, each blocking creature can only block one attacking creature. Some creatures have a mechanic that allows them to block extra creatures (This creature can block an additional N creatures each combat.). This mechanic used to be primary in white and green. This is an ability that R&D has stopped using for various reasons, but mainly due to digital concerns.
===Can't be blocked===
Can't be blocked (AKA Unblockable) is primary in blue.
===Can’t be blocked by creatures with power 2 or less===
This ability, nicknamed Daunt, appears irregularly in green.
===Can't block===
The "Can't block" drawback is primary in black and red. For a long time R&D separated black from red by making black have the "can't block" drawback on its creatures and red have the "must attack" drawback on its creatures. Time has shown that the "can't block" drawback leads to better gameplay, so they've started using it on red as much as black. It is a way to allow for a larger volume of tokens without bogging down the game, such as with decayed zombies, and Rats in Wilds of Eldraine. In Phyrexia: All Will Be One it was also used for white Mites.
===Deals damage when blocked===
This ability is usually found on red creatures. When black does it, it is usually loss of life. Afflict also does this in blue.
===Forced block===
Forced block (Target creature must block this turn.) is seldom used but is primary in green and secondary in red.
===Damage assignment order (obsolete)===
Under this rule, immediately after blockers were declared, both players announced the order each of their creatures would deal damage to any creatures they were blocking or blocked by, in cases where there were multiple such creatures. This created more predictable damage assignments during the subsequent combat damage step, which made it easier to play damage prevention or redirection effects to their full potential. Such effects would be played during the declare blockers step, so that replacement effects that change how damage is dealt would be active when combat damage occurred.
This rule was removed when the comprehensive rules were updated for the release of Foundations. Assignment of combat damage among multiple creatures now happens during the combat damage step.
