XYZ Support

Pay 1000 Life Points and select one face-up monster on your side of the field. If used for an XYZ Summon, this monster counts as 2 monsters of its level until the end of the turn.

Overlay Resurrection

Select one Face-up XYZ monster on your side of the field. For this turn only, if that XYZ monster has no Overlays, the Zero Overlay effect drawback is negated. Destroy the selected XYZ monster at the end of the turn.

Soothing Space

Black Hole Seal
Counter-Trap
Activate only in response to the summoning of an XYZ monster. Negate the summoning and remove the XYZ monster from play. The summoner cannot attempt to summon another XYZ monster for 3 turns. This can only be used once per duel.

Very nice cards. I think Black Hole seal is a bit overpowered. maybe instead, the effect could be
"Activate only in response to the summoning of an XYZ monster. Negate the summoning and remove the XYZ monster from play, as well as the cards used for its summoning."
this was the xyz monster as well as its material's are removed from play instead of just the xyz going to the grave.
