As a general rule I would start to avoid colourless lands when I get to double figures of cards with no colourless or at around 65-75% ratio of coloured mana requirements on spells to colourless
That said, it would be nice to see different cards slide into the future reprints
Its an additional tutor plus has a very powerful amplification ability
A new card type, inspired by Final Fantasy summons like Shiva, enters the game with a lore counter, gives an instant effect, and stays for a few turns before vanishing, copying the short but strong nature of summons
When Rampaging Yao Guai enters the battlefield, destroy any number of target artifacts and/or enchantments with total mana value X or less
It is fine as red monsters go but not really offering anything new or overly powerful to the colour
