Collectible Card Game Headquarters

I want to make the Opalescence.
I make a creature card with Second type is enchantment to test, when the spell resolves, it will stay in the middle of the game screen, and game can't continue also.
How to solve this problem?

Such type of cards is provided in game, but up to the end is not realized, "compound-type". They have no truly set site in game, and on it jam about a midfield.Such card it is possible to play - to attack, be protected, but at usual click of the mouse - for viewing of the text of a card or activation of ability - game hangs. Now it makes sense to do only variants with short-term change of card-type, zum Beispiel - "until EOT".
