You don't need fancy templates. Morph works on any two slides with shared objects. A free template just gives you pre-named objects (e.g., "Title_1," "Image_2") so Morph knows what to animate.
The best free templates teach you how PowerPoint "remembers" objects between slides. Once you see that, you can morph anything : a pie chart into a bar chart, a logo into a full-screen image, even a bullet list into icons.
If you need to show processes, cycles, or timelines that actually move and flow, SlideHunter is a solid choice.
Your presentation looks like a high-quality video or GIF, rather than a deck of cards.
