This deck pretty hard to run, but the main gist is to try to swarm the board with many creatures till your opponent is out of cards, pressuring them by slowly biting on their health. Cards like Marked Man, Fifth Legion Trainer and Corsair Ship along with the other Token generators are the combos.
Once you have Chanter of Alkatosh online, you have many options. Like Altar decks, the knowledge of how many cards of a certain Magicka cost you have in your deck left is key to playing him. You probably don't want to play him on turn 5, but try to get him out on the turns after that where you can get him to proc at least two times. I would like to also add that if you don't have any copies of a particular Magicka cost in your deck, it will generate a sweetroll instead, which still has usefulness for Cruel Firebloom and synergy with the other Token buffers. Killing people with sweetrolls is fun.
Alkotosh card fetching:
0- Nothing intially, but later Elusive Schemers.
1- Marked Man for the combo. Preferably when you have Corsair is out. Mulligan him out.
2- Fifth Legion Trainer and Shimmerine or Bruma. Combo them with Ice Spike while chanter is out.
3- Crushing Blows fetch Cunning Ally and Eastmarch Crusader. Best cycle and board presence combo.
4- Lightning Bolts and Imperial Reinforcements fetch 4 cost Elusive Schemers.
5- Piercing Jav fetches other Alkatoshes or Ayrenn.
6- Ice Storm a board with Ward on Chanter grants you Stealer of Secrets.
Do not play this deck too aggro, proc the first rune and deal with their board. Feel free to switch around the ratio of combo cards and maybe include a Stealer of Souls for endgame win condition.
Updated with Mulligan and changed list to remove Golden Saints.
Updated 2: Added Soul Split for more two drop fetching and Telvani to even the curve a bit. Reduced Marked Man to one.
Update 3: Changed a whole lot of cards adding in more blues to proc Cunning Ally. Deck now plays more control to go with the meta.
Update 4: Stealer of Secrets try and returning Fifth Legion again.
Try to get a Schemer in your hand, Shimmerine or Corsair Ship. Marked Man is bad and generally try to get creatures in opening.
