Any card abilities which happen when a player pays a cost to use them (activated abilities) or automatically when specific conditions are met (triggered abilities) must also pass through the stack and can be responded to the same way (though you would need a card that says target ability to interact with one)
The linked article does in fact state that, and it is technically correct, but it's a completely inane statement
Whilst this card has the useful Ward keyword - meaning that it cannot be targeted by anything but a challenge - what makes it really shine is its ability: Spare Parts
Not only this, but Samut is also stacked full of keywords, with First Strike, Vigilance, and Haste making it easy to get the speedball rolling and maintain a steadily building speed
Conclusion ** VIDEO SPOILERS ** *** VIDEO SPOILERS *** The deck
Lets not get too negative, though
