By Temple High Guard do you mean the Asyran Defender or Joseph Trueblood or another card I'm unaware of?

You're worried about promoting degenerate play in a game where the goal is to kill the opposing mage? I'm sorry. I just don't get that. I understand putting errata on a card if there's a major issue with the balance it cause. Teleport is so far from causing issues with balance though, I can't believe this is a thought. If you're so worried about teleports being a factor on your mage, add more nullifys or add your own teleports. I just think people want changes based on their own experiences whether or not they make sense to the game as a whole.

Is the Asyran Defender the only Holy school card in the set because that would suck as someone who likes playing the Priestess. I know she's one of the better mages as is, but another card or two is always useful.

Had the tournament today and made the changes mentioned for the most part, adding in some nullifys and dissolve with some other stuff while taking out the creatures. I had put in a Bim-Shalla, but didn't play it in any of the 3 games and just never see the opportunity to get it out so it helps, but maybe in time.

As for results, I won the first match in a drawn out passive game against a Warlock but had the build to really do some damage in the next few rounds. The second match was just a massive beatdown against me by a fellow Priestess. My attacks didn't do the damage I needed because of the armor my opponent put up which put my attacks down multiple dice and after he destroyed my Temple of Asyra in a very early round, I was battling from the defensive all game. I was able to survive until the time limit but lost due to damage sustained. And in the 3rd round, I made a few crucial mistakes against a Necromancer and wound up getting knocked out, but won a secondary condition that was added specifically for the tournament by lasting 5 consecutive rounds in the opponents starting space. Moral victory, I suppose.

I think I need to change up an attack or 2 because being so dependent on Lightning really becomes an issue if my opponent brings out an Elemental Cloak & Storm Drake Hide. Other than that, I think my biggest problem is I'm not a very aggressive player so I plan the first few rounds all around getting out Mana Crystals, Battle Forge, & Temple of Asyra with my Clerics to build up Mana but if I'm facing anyone aggressive like I did today with the other Priestess & Necromancer, I basically have no offensive capabilities and getting out my own equipment takes a bit of time with the Battle Forge.

Here's my normal opening so I'd like some advice on what to do strategy wise since I like the deck for the most part now:

Round 1 (20): Mana Crystal in the space above me, move to the center and either Battle Forge in that location or Temple of Asyra in a corner

Round 2 (18 assuming Forge): Temple w/Harmonize or Forge and then Harmonize Temple either way.

Round 3 (15): Altar of Iron Guard in the other corner and Asyran Cleric w/guard token

Round 4 (17): Here's where I suppose I need to figure out the best plan, I've been doing a Guardian Angel since he comes in with a guard token, but not sure if I should just save my mana now to build up for some other stuff. I'll use my Cleric going forward to add Mana to the Temple but in general, I need to know if I'm doing something wrong with this start or how to manage better. Should I forego the mana crystal and just get right to my spawnpoints and clerics quicker to get bigger fighters out sooner?

Yea, it probably is a bit too creature heavy, but I really like the options depending on the opponent I'm playing. If I'm playing someone who wants to hang back, I can bring out the Archer's with the Watchtower and attack that way or if they're a bit more agressive, I can bring out the Guardian Angel and Valshalla. The Knights and Brogan are just useful all the way around. What I should probably get rid of is the Defender and one of the Clerics to add some of the stuff you mentioned. I should also probably get rid of Samandriel for some added flexibility with the spells you mentioned but I'd hate for it to come down to me losing too many creatures and then not having any real offensive firepower left since the Priestess herself doesn't have a great attack.

I had a question regarding attacks, since I only have the two, is the Elemental Wand even worth it since it's likely to get Dissolved. Or should I add more attack spells even if they're cheaper like the Pillar of Light and simpler things like that?
