Question about WC3 models

[BrothForMyPeople]

Hi

I own only Wings of Liberty. I didn't buy next expansion because I don't like playing Zerg, especially rpg Rexxar campaign-style as it is. With time I forgot about SC2 and I skipped Protoss campaign as well.
As for the question: can I use WC3 units in Starcraft editor having just WoL?

NVM, it's self solved.
For others: Yes, free-Starcraft 2 DOES contain WC3 units.

Just to add to this topic. One can access and use all mods as long as one meets the requirements to use the editor. Currently it seems these are locked to only the HotS and LotV campaigns (WoL is now free). There is much argument over if this is fair or not since some documentation says the editor requires any purchase, and not just the other 2 main campaigns.
