Having cards like this gives you more flexibility when you are limited on the amount of cards you can run (100 or 101 in the case of my MTG Aristocrats Companion Deck)
Its not the easiest way to get an additional combat compared to the other cards on this list
Spacecraft need to be stationed by using creatures to add charge counters to the artifact until they reach a certain minimum and they count as a creature
With cumulative upkeep, you have to add an age counter to the card before paying its upkeep cost, then pay the cost separately for each age counter
Finally, Freyalise's -6 ability will draw lots of cards with a board state full of Elves, and getting enough loyalty counters for that ability should prove easy in most games.
Note that the counters on battles are defense counters, not loyalty , but since they work in a similar way to loyalty counters on planeswalkers, the confusion is understandable
