Picture into Card

{Tesgak}

I think everything is costed correctly? Although, it could probably enter untapped, unless the intent was to make summoning sickness less confusing. I’m uncertain about the wizard rider as well- casting and then animating an artifact is not something I’d picture in wizard tribal. Maybe gaining a bonus if you control a wizard instead? Or even a creature of a certain color?

I searched and brainstormed for a while about whether this was a green effect or not. My conclusion: no. The “artifact reanimation” effect is most common in white and blue, with white also having a number of cards that recur artifacts to hand (red also has Trash for Treasure and black barely squeaks in on Sharuum). Green… doesn’t have either. If Revitalise said “permanent” (and thus cost more) it would be in an arguable state rather than a pie break.

Disclaimer: I have never plaeyed planechase.
Looking at existing phenomeons (phenomena?), they seem to be balanced such that they don’t favor a particular deck (well, other than the boardwipe helping fewer-creature decks). In 60-card casual multiplayer, it’s possible for a deck to play no artifacts and get no benefit, and while planechase commander may have more artifacts, it also has a higher potential for artifact-centric decks. At the same time, planechase is a house format so whoever sets up the planar deck can choose whether it should be included.
I do like the overall idea of the card, since being a creature can be an upside and a downside. It is kind of awkward how it makes potentially larger creatures 4/4, though.

I believe this is undercosted- the closest approximation is Leafdrake Roost, which requires a “3” mana investment for every token, is in two colors, and doesn’t have the benefits inherent in a fortification. Other effects such as Spawning Grounds and Sandwurm Convergence are eight mana but are less similar to the Titan. I’m also not convinced that it needs hexproof from green, as even if the land is destroyed (unlikely) the Fortification can be refortified (which is apparently a real word).
I like the overall theme of a deadly mechanism re-arising, but I’m not sure the flavor connects since multiple titans can be made by different lands. Is it one titan churning out little ones?

More often than not, the tapping and freezing effects will be the most useful. However, I do like that you can use it with mana rocks to get some value back. Personally, I would like to see it as a 3-mana sorcery since as-is you can cast it upkeep and deny them over for another turn, but since they have the opportunity to respond I’m probably overthinking it. In a similar vein, it has the potential to be monoblue.

Artifact animation is… arguably a green effect, but certainly not a white one. This could also easily be an instant compared to Ensoul Artifact, which creates a bigger, permanent dude.

I like the overall versatility on this. It can be a 4 mana reanimation spell and also a persistently value-generating beater, but the cmc requirement limits the usefulness of both.
6/7 is a pretty big statline, but crew 5 is a very significant requirement (which also serves to limit the value generated on the field). My main complaint is that it doesn’t feel green- heck, if you told me it was three colors I would guess esper.

If I had to pick two colors for this card, I would go with white and blue. The times black and green have gotten artifact/enchantment recursion that type was a focus of the set. I could see this as “up to two target permanent cards with different types” potentially at 3 mana.

{ZephyrPhantom}

The art doesn’t feel super red, but this feels like a nice “fixed” version of Ball Lightning/Spark Elemental variants. Since it can eat attacking creatures, it’s no longer a dead card when the opponent has a large board presence, plus as an instant it synergizes well with… cards that synergize with instant/sorceries. 5 power for 3 mana seems to be the correct rate as well.
