I understand the win streak argument, but if you look at the matchup tables at https://gudecks.com/meta/matchups?god=deception&timeFrame=7&userRank=10 you'll find the Deception decks that have an overall win rate against other archetypes above 50%. In the case of Solar Gold and counting 7 days worth of matches, Mayday, Hidden Rush and Aggro have win rates above 50%. The latter 2 are generally pretty cheap decks. You don't get these numbers with win streaks only, these percentages take into consideration matches for all players.
