The fight to get into Dragonspyre (Professor Cyrus Drake) is nearly impossible for Storm Wizards. He should not know the Storm Shield Spell. This spell makes it way to near impossible. The fight goes like this: I save up for Triton; no shield. I get to Triton. No shield. I cast Triton. Shield. It's like the game AI is absolutely buffed on this boss monster. Also, his personal attack where he hurls beams of light at your face for two pips, is much too overpowered. Thanks
Honey, I beat Cyrus Drake first try level 48 conjure. Just spam some minions here and there, use a little reshuffle, some treasure cards; and tada you beat Cyrus Drake.
Neither storm nor myth should have any issues with Cyrus.
By the time you face him, you should have trained prism, a solid rank 3/4 secondary school damage spell (I personally recommend death for its versatility), and any of Shatter/Pierce/Cleanse Ward.
If you know you will be facing a myth boss, what do you usually do? You optimize your deck and round out your sideboard. Cyrus is no different, and he still takes a hefty percent more damage from storm.
The only thing that's different between Cyrus and say, General Akilles is that Cyrus has a lot more health and will occasionally cast a higher level spell or one from a different school.
So you will have to be able to heal and shield, as well as use prism or shatter to take down his defenses.
I think a lot of folks are intimidated by the fact that he's the Myth Professor, so they play too conservatively or they overload their deck with contingency plans - and never draw their good damage spells.
Use max number of prisms Train or buy reshuffle. Blade/trap after prism, but before every hit if you can. Be careful using minotaur through prism. The first (smaller, shield-wiping) hit will be prismed, but the larger one might not be. Sideboard medusa tc Sideboard kraken/triton tc and a satyr.
Use a storm wand that gives you an extra starting pip. Use the storm hits to scrub off the shields that went up BEFORE your prism - any storm shields he puts up AFTER you've prismed him, are safe to ignore until it's time to prism him again. DON'T waste storm wand hits trying to whittle him down. These are to zap shields unless he is so low in health the wand hit will kill.
If you're storm just remember to save wand hits for zapping away shields. If you're going second, rely on spamming the lower-rank spells rather than winding up for a big finish, because he always manages to slide a ninja storm shield between himself and your bladed tc leviathan. Ignore weakness.
For me he wasn't too hard. It took me two tries, it would be one but I ran out of cards and forgot to put in treasure cards the first time, and the second I got lucky and drew a stormzilla treasure card when I ran out of cards. I had boosted, he had no shield, so I hoped, and sent it at him. It hit a lucky 2000+, and Cyrus was dead.
