We knew Elyse would be a bad card, but fun to play.
Elyse herself isn't an awful card, 3/5 for 4 is decent.
The Map can be pretty bad though, it's 2 Mana to do nothing. It also means you're drawing this instead of something more useful.
I had a game I lost on the turn I drew the map...not saying I would have won, or even survived if I had drawn something else...but there were cards in my deck that could have helped me survive a turn or more.
The Monkey is pretty good, 6/6 taunt for 4.
The thing is, aside from coolness factor having your hand and deck become all legendary ended being bad, more often than not.
In one game, it was just a win more card.
In 2 games, I couldn't play it because my hand was too good, and ended winning within 2 turns.
In the other games, it basically didn't really much of an impact, or had a negative one. Basically, you end up playing 1 big minion per turn only...you have no more removal. It's ended up being a huge tempo swing in favor of my opponent.
At no point, did drawing the Golden Monkey became the winning play, or game changing draw.
It just kinda suck, even more than I expected...because it's so bad that it's not actually all that fun.
The concept is interesting though, the payoff is just not worth the trouble...as I said most of the time, I ended up in a worse situation after playing the Monkey.
