Heh. Funny setup.
When you cast
Infinite Reflection
on
Ixidron
(well, when it resolves), your face-down
Willbender
becomes an Ixidron. The board now includes:
Opponent: Face-down 2/2 colourless creature (face-down
Hill Giant
)
You:
Ixidron
with
Infinite Reflection
attached
Face-down 2/2 colourless creature with a copy effect settings its copiable values to Ixidron (face-down
Willbender
that can't be turned face-up)
The odd Willbender-thingy is still face-down, so it's still a colourless typeless 2/2 creature. You can't turn it face up because the copy effect is overwriting its characteristics so it wouldn't have a morph cost if it were turned face up. If it were turned face up by something else like
Ixidor, Reality Sculptor
, then it would still be an Ixidron, but now a face-up one, so the real Ixidron would be one smaller.
When you cast another creature (say
Giant Octopus
), things get a little sillier. That works exactly as if you'd cast another
Ixidron
, and so the board after it ETBs looks like:
Opponent: Face-down 2/2 colourless creature (face-down
Hill Giant
)
You: Face-down 2/2 colourless creature with
Infinite Reflection
attached (face-down
Ixidron
)
Face-down 2/2 colourless creature with a copy effect settings its copiable values to Ixidron (face-down
Willbender
that can't be turned face-up)
Giant Octopus
with a copy effect making it an Ixidron
Your Willbender is as it was, but the Octopus is now a copy of Ixidron, so it's 3/3.
Amusingly, any further creatures you cast enter the battlefield as 2/2 colourless creatures even though they're not face-down. Suppose you cast a
Quicksilver Dragon
, the board would end up as:
Opponent: Face-down 2/2 colourless creature (face-down
Hill Giant
)
You: Face-down creature with
Infinite Reflection
attached (face-down
Ixidron
)
Face-down 2/2 colourless creature with a copy effect settings its copiable values to Ixidron (face-down
Willbender
that can't be turned face-up)
Giant Octopus
with a copy effect making it an Ixidron
Quicksilver Dragon
with a copy effect making it a 2/2 colourless creature with no types or abilities (but not face-down)
