I've already spent 200,000+ MGP on gold triad cards and have not seen a single 5-star. It makes me feel like I should have just saved up for the Cloud card first. Seriuosly, they need to add something to the packs with a higher drop rate that you could at least save up and trade in for one of the 5-star cards. At least that would make me feel like I'm making progress. (That goes for the 5-star trials only drops as well)
