Isshin, Two Heavens as One's ability affects only triggered abilities with conditions that are directly related to attacking, such as "whenever [this creature] attacks" or "whenever you attack with one or more creatures." It does not affect triggered abilities with other trigger conditions, such as "whenever [this creature] becomes tapped." Isshin's effect doesn't copy the triggered ability
You need the card to survive in order to assess how effectively it is contributing to the win
I find the hate for it to be very silly and find the archetype incredibly fair, especially compared to what your average Artifact, Lands, Enchantress, Treasure / Food / Clue deck is doing these days
This Goblin isnt weirdly normal, though its anything but
Having this buddy sat on the board will give virtual card advantage by the bucket load, too, and will force opponents to spend removal to solve your failsafes
That bodes well for my plan to build this as an Elf deck rather than some other sort of deck with a few Elves thrown in
