Plane — MagicCon
Whenever
a
player
casts
their
commander
or
attacks
with
their
commander,
they
may
say
"Only
one
may
stand."
If
they
do,
that
commander
becomes
a
Knight
in
addition
to
its
other
types
until
a
player
planeswalks
away
from
Game
Knights
Live.
Knights
you
control
have
double
strike
and
trample.
Whenever
chaos
ensues,
commanders
you
control
can't
be
blocked
this
turn
and
gain
"Whenever
this
creature
deals
combat
damage
to
a
player,
draw
a
card"
until
end
of
turn.
