A four-ink card, Mrs Judson, Housekeeper, has some excellent stats one strength and five willpower - for what the card is best used for, which is getting as much additional ink into your inkwell as possible
Whenever it attacks, it turns a creature into a copy of it, or can turn a land into an Island to make sure you can always attack without worrying about it being blocked thanks to Islandwalk
Its also hard to take advantage of this effect, but if you have fewer lands than your opponents, theyll sacrifice more in the long run
Its also not lost on me that a blue artifact looking to yoink spells from your opponent probably doesnt want to target the other blue player - for the risk of running into a counterspell which will be a pointless hit to get unless youre activating Synthesis Pod in response to an already ongoing stack war
In the various three or more coloured versions of UG control decks I would always chose to play a Negate over an Actual Counterspell, those kinds of deck have an unrivalled ability to deal with permanents while coloured mana is more of an issue
