I have played Wastland Wraith in a couple of decks.It is pretty hard to use effectively but I have played it in my control Ciyphron deck whose goal is reach turn 9 for Monthlitic Vision with very small amounts of success. So this is what the card is best at in my opinion.On Turn 1 you play a minion you don’t care about because you just want to grab the tile for Wasteland Wraith. Turn 2 when you grab the tile play the Wasteland wraith as far back as possible and move forward.This what it causes
The if the person removes the wasteland wraith you win they had to use premium range removal on a minion that is dying anyway and you have better threats in your deck and they likely wasted a turn.
More than likely the opponent isn’t going to do anything because any minion they play is going to die.That is the outcome you are looking for because you basically want to restart the game.With you having the attacking advantage.In most cases you will have a 5 mana turn because to stop you from getting the tile they have play a minion which would be a waste.
This is the only time Wasteland Wraith behaves how it is supposed to because some early removal can’t remove it and even if it can it is waste to use removal it. This card is case of why mess with already works in HS Doomsayer is a 2 mana 0/7 “At the start of your turn, destroy ALL minions”. The cost and the amount of health were key in the card working in HS. In Duelyst Wasteland Wraith comes out later and has less health which works against it.
The problem with card it is not really supposed to be removal.If the opponent has a massive board they will use removal to keep their board so playing it is a death wish in Duelyst especially with all the cheap 2 mana or 3 removal in the game. Wasteland Wraith is supposed to be a proactive stall card that discourages aggro decks from developing early. Wraith needed to be cheaper probably 2 mana or 3 mana so it could be played proactively early or combo with a another minion for the dilemma of removing it still leaves a board. Sporadically you finds points where you can play it or they don’t have removal but mostly this is not a good card because it is too expensive to be played proactively
