We investigate the ground state properties of $^{22}$C by using a deformedrelativistic Hartree-Bogoliubov model in continuum and explore the interplaysamong the formation of a halo, deformation effects, the inversion of $sd$states, the shell evolution, and changes of nuclear magicities. It is revealedthat there is an inversion between the two spherical orbitals $2s_{1/2}$ and$1d_{5/2}$ in $^{22}$C compared with the conventional single particle shellstructure in stable nuclei. This inversion, together with deformation effects,results in a shrunk halo and a quenched shell gap at $N=16$. It is predictedthat the core of $^{22}$C is oblate but the halo is prolate. Therefore severalexotic nuclear phenomena, including the halo, the shape decoupling effects, theinversion of $sd$ states, and the evolution of shell structure which results in(dis)appearance of magic numbers, coexist in one single nucleus$^{22}\mathrm{C}$.
