Drew Tucker's Grim Tangle was commissioned for Sorcery under that original name but was changed to what we now know as Entangle Terrain in the Alpha/Beta set. This curio provides us a clue as to the development stage of the game circa 2019. You'll note that the footer information on this card starts exactly the same with "KS2019 Full Art 25/300". The "KS" is presumed to be "Kickstarter". The year is the approximate timeframe when this work was commissioned, and interestingly the set number is exactly the same as the Bloom of Frogs Curio card. This would seem to reinforce the point made about common template usage to frame illustrations relative to text boxes.
There are a few distinct differences that we see for the first time:
New element resource symbols in the upper left title box
The threshold symbol and cost in the right side of the title box, separate from the element resource as it now pairs today in Alpha
The circle / pie chart symbol as part of the gameplay mechanic
Type line text ("Continuous Event") positioned below the game mechanic box instead of above
The "Continuous Event" mechanic that no longer exists
The set symbol highlighted in gold, as opposed to white in the Bloom of Frogs Curio card
