[The card in question]

Currently, this card's text is listed as an unclassified effect. If it was negated by, say, Breakthrough Skill or Skill Drain, would I still be able to successfully use it in a Synchro Summon as a non-tuner? Why or why not?

Furthermore, is there any way to word an effect similar to this, so that the effect would be a Condition?

Thank you for your time.

It's similar to "Tuningware (http://yugioh.wikia.com/wiki/Tuningware)". So if the effect is negated, it can't be treated as a non-Tuner, just like if you Summon "Tuningware" from the Graveyard with "Junk Synchron (http://yugioh.wikia.com/wiki/Junk_Synchron)", you can't treat it as a Level 2.

It's Unclassified because it's "not an Ignition, Trigger, Quick or Continuous Effect. (Applying this effect does not start a Chain Link.)". The wikia points this (http://www.db.yugioh-card.com/yugiohdb/faq_search.action?ope=4&cid=7986&request_locale=ja) as the source.

Also from Unclassified Effect (http://yugioh.wikia.com/wiki/Unclassified_Effect): "Unlike conditions, they are card effects, so they can potentially be negated."

In the OCG, to be a condition, it would have to be written before ①. But since this card as never been reprinted since those were applied, you can't check it. "Tuningware (http://yugioh.wikia.com/wiki/File:Tuningware-SD28-JP-C.png)" does have it after the ①, just like this card would.
