Skytear Horde: Monoliths - Solo Tutorial & Playthrough

About Skytear Horde, from BoardGameGeek:

Hordes of monsters are attacking the world of Skytear and the legendary heroes from all four realms have forged an alliance to repel the common threat. Skytear Horde is a lane-based card battler in which one or two players fight against the horde of monsters controlled by the game. In the competitive game mode one player controls the horde while up to two players fight together as the alliance. Players say Skytear Horde gives them the feeling of playing a solo or cooperative version of competitive card battlers such as Keyforge, Hearthstone, or Magic: the Gathering. In the six lanes of the battlefield monsters attack your castle while beyond the enemy line smaller minions pillage your resources, forcing you to discard cards from your deck each turn. You lose the battle if your castle is destroyed or your deck runs out of cards. You win if you destroy the portal spawning the monsters and the epic monster leading the horde. There are many interesting choices on the tactical and strategic level: strike a balance between defending and counter-attacking but also fighting the minions pillaging your deck and the monsters destroying your castle. While you juggle all these decisions you also have to be careful not to run out of cards, as the principal way to draw new cards is to destroy monsters! Skytear Horde is really quick to setup, play, and store away. There are 3 difficulty levels suitable for complete beginners and veterans alike. In just a few seconds you can restart a new game giving it a strong "just one more try" aspect. Out of the retail box there are 3 ready-made alliance decks with different play styles and 3 horde decks with their own boss. All decks can be mixed and customized to provide additional combinations.
