Ah, so far this reveal season reminds me of the glory days when most legendaries in an expansion sucked, only 3 to 4 legendaries were playable, and maybe 1 or 2 were must crafts. Remember GvG and TGT? I'm not complaining, just means i could save a boatload of gold and dust for the next expansion.
Surprised no one else is touching up on this, but what if you WANT your opponent to take advantage of the zero cost and trick them into playing one of their big threats? I view this more as a bait card - you're tricking your opponent into playing one of their big threats, and punishing them in kind next turn even if Duskfallen Aviana is killed. This card is meant to punish players for playing greedy - I'd follow this up the next turn with a Naturalize and laugh at their salty tears as their precious Lich King or Tirion got nope'd.
This one is a sleeper card, I am laying you odds. It's a card designed to play chess with your opponent as he wonders if it's okay to slap his big threat down or if he should kill Duskfallen Aviana because they suspect that they are playing right in the Druid's hands if they kill off a big threat two turns sooner. I'd be an idiot for underestimating this card.
Wow! I hope the tag line is: Terrible, Terrible Damage! 2 things about this card though:
1. I feel sorry for anyone who gets this a their free legendary. If I were just starting out as FTP and got this garbage, I would probably uninstall. This cannot end well for you Blizzard in trying to widen your player base when you make legendaries this bad.
2. The Honest Hearthstone Card version reads: " You are putting Fireland's Portal in too many of your decks and playing it too often."
