[/spoiler] [spoiler= Heavy Freight Train Derricrane] If an EARTH Machine-Type monster(s) is Normal or Special Summoned to your side of the field (except during the Damage Step): You can Special Summon this card from your hand, but its original ATK and DEF are halved

The sets self-aware nature (Its complicated, it says knowingly of Pendulum summons), measured approach to rolling out rules a little at a time (some steps set up later turns, advising the player not to worry about the details until they need to) and lighthearted tone make it feel more like a friend taking you through the ropes
I cant even abuse the trigger by casting a Pyroclasm and getting several triggers at once, so Im really not happy with this
