2. Identifying replacement effects
● Like activated and triggered abilities,
replacement effects use their own
characteristic templating
● Unlike these types of abilities, there are more
types of templates that are used, and they
aren't as strict
20. Replacement effects:
Existence vs. application
● One thing that can be confusing is that
replacement effects need to exist before they
apply.
● Sometimes, the replacement effect is set up
by a static ability that's just on all the time.
Other times, we're not so lucky...
25. How do replacement effects work?
● Once a replacement effect exists, it constantly
watches the game for a chance to apply and
intervenes immediately when it sees one.
● Replacement effects don't require priority or
use the stack. They can apply anytime, even
in the middle of casting or resolving a spell.
● If the replacement effect involves a choice,
that choice is made as the replacement effect
applies.
30. CR 117.11
● The actions performed when paying a cost
may be modified by effects. Even if they are,
meaning the actions that are performed don't
match the actions that are called for, the cost
has still been paid.
31. Interaction of replacement effects
● If two replacement effects want to affect the
same thing at the same time, the affected
player or affected object's controller chooses
what order they apply
● A replacement effect can only apply to a
specific event once. This is true even if the
replacement effect still applies to the event
after applying the first time, or if applying
subsequent replacement effects causes it to
become applicable again.
34. Interaction of replacement effects
● The affected player still gets to pick, but there
are some rules they have to follow.
– Self-replacement effects are the highest
priority and must be picked first.
– Then, effects that make a permanent enter the
battlefield under a different player's control
– Then, effects that make a permanent a copy of
another permanent
– If there are none of these, the affected player
can pick whatever effect they like to apply
first.
37. CR 702.33
● "Flashback [cost]" means "You may cast this
card from your graveyard by paying [cost]
rather than paying its mana cost" and "If the
flashback cost was paid, exile this card
instead of putting it anywhere else any time it
would leave the stack." Casting a spell using
its flashback ability follows the rules for paying
alternative costs in rules 601.2b and 601.2f-h.
40. Summary
● Look for characteristic templates like “instead”
or “skip” or characteristic effects like changing
how an object enters the battlefield or is
turned face up
● Replacement effects have to exist before they
apply, but they can apply anytime, without a
player needing priority or using the stack.
41. Summary
The affected player gets to choose which
effect to apply first, but must respect the
replacement effect “layers”
– Self-replacement effects
– Gather Specimens
– Enters the battlefield as a copy effects
– Everything else
